Blocks

 * [!] While making an entire stack of, the game will.
 * [X] When a block is placed with empty space underneath, a column of source blocks are created under the original source block.
 * [X] s can be gathered by placing a block directly beneath them.
 * [X] s appear inside of s when you sail over them.
 * [X] Two s set beside each other will have a line dividing them on one side, but be clear on the other side.
 * [X] If you build a tower(≤ 12 blocks) on a, connected to a , most of the  will disappear after a couple of pushes.
 * [X] Using an with the  on a pine or birch  will only drop oak  (not pine or birch ). The same happens when mining  and  s with  - you get normal s. It seems that dropped item doesn't remember durability of the block mined.
 * [X] Diamond armour does not protect you from damage
 * [X] and  drips through  if there is  or, respectively, above it.
 * [X] s break with a single hit and are destroyed permanently if not using a.
 * [X] It is possible to place in water.
 *  [F]  While in the inventory screen, has a tooltip of "Unnamed".
 *  [F]  s are not affected by the shades.
 *  [F]  The blocks can be broken without the surrounding portal blocks disappearing. The expected result is either the portal block respawning, or the portal itself turning off.
 *  [U]  Blocks are not always what they seem to be. For example, a block can look like a  block. If you destroy the said block, you get the  block. Placing a  (or right clicking with a sword while aiming at the block) shows you the real block. Some details that may be important is that the chunk may need to be newly generated and running on SMP with some latency.
 *  [U]  If a is activated when joining a world, it will stay activated until you destroy it or quit.
 *  [U]  does not push ignited  blocks or s.
 * [X] You can place blocks on fire even when you are in the fire. Video explaining:

Crashing
This works with 64-bit OS machines: "%ProgramFiles(x86)%\Java\jre6\bin\java.exe" -Xmx256m -Xms128m -cp Minecraft.exe net.minecraft.LauncherFrame Use this line for 32-bit OS machines: java -Xmx256m -Xms128m -cp Minecraft.exe net.minecraft.LauncherFrame
 * [!] After a, seem to disappear from all items in the.
 * [!] After a few minutes of playing, the game runs out of memory or freezes. This often happens while running 32-bit Java on a 64-bit OS. This can commonly be fixed by using the below line in a file ending in .bat or .batch.
 *  [F]  [!] Trying to access the "Video Settings..." menu in-game causes the game to crash with a "Saving Chunks" screen. Trying to access it from the beginning game menu gives a black screen.
 * [?] When going into the Video Settings tab while paused, it crashes the game.
 *  [U] [!] Sometimes, the game crashes when the attacks a.
 *  [U] [!] Occasionally, the game displays switching worlds then crashes.
 *  [U] [!] Sometimes, when mining with an , the game es with a "Saving Chunks" screen as opposed to the usual error report or black screen.
 * This happens with an  if the  is Fortune and the level is larger than level 3 while dropping a piece of.

[U][!] Sometimes, the game crashes when the Player attacks a creeper Updating Minecraft Done loading
 * [X] My game cannot update minecraft 1.9 pre, it got stuck, when it shows:

Gameplay

 * [!] Clicking/right-clicking while moving the mouse may cause the screen to lose focus. Seems to happen in all OSs but it happens even more in Linux with the Fluxbox window manager. The cause is that whenever you click or right-click, the game loses cursor focus (you can even see the cursor blink over the screen). If the cursor is moving enough fast, it is not relocated in the center of the screen in time. Like the mouse locking does not work very well. Very easy to reproduce (easier in Linux&Fluxbox window manager): Just spam right-click while moving the mouse fast.
 * [X] If you land on the bottom of the while in a  in, the  will disappear but may leave you perfectly safe to walk around. Any jumping will cause you to start taking damage normally.
 * [X] When you place a block next to a and stand directly in the space between the  and the new block and destroy the block next to it, you can walk inside the.
 * [X] Planting a on a  block in  will result in an invisible  once  has been applied. This can be fixed by breaking one of the blocks, at which point the  will reappear.
 * [X] You can only make Splash Potion of Regeneration II with the "correct" recipe.
 * [X] If you sit in a on s and save and quit to the title and play your world again, the  will duplicate.
 * [X] -triggered mechanisms such as Doors don't operate properly returning to  from the  until the es are removed and reset.
 * [X] s are done to s when you punch one when your sitting in it.
 * [X] The inside corner of a corner block does not have the correct bounds like a normal  block or the outer corner of said block.
 * [X] If you place a block under tilled, the game registers you as walking on the , and subsequently does not damage the  because you are not walking on it.
 * [X] Double tapping the crouch key (default ) and releasing will cause the to  with seemingly no effect on the  meter.
 * [X] does not detect when  powered items are adjacent while it does detect s.
 * [X] s do not receive power from adjacent blocks that are powered by, while everything else does.
 * [X] Creating anything on a using shift-clicking to move it to your  does not add anything to your statistics.
 *  [F]  When picking up all the lost s after death, you seem to get more points that you had before.
 *  [F]  When, swapping the ingredient at the very last second before it is applied will apply the ingredient you changed it to rather than restarting the brewing timer for the new ingredient.
 *  [F]  are not affected by the movement speed modifier of the Splash Potion of Swiftness levels 1 and 2; s still function properly.
 *  [F]  When you drink a Potion of Fire Resistance and try to swim in, this does no damage to the , as intended, but when you jump into a lake from a large height, the fall damage you would receive is saved up until you exit the lake.  Death can probably be avoided with a.
 *  [F]  If you place an item in a  or  and then break it, the  will be gone.
 *  [F]  After you a  in, when you try to , the  will rapidly switch from the  stance to the normal position. It does not happen for normal.
 * [?] It is possible to position the camera in such a way to view systems.
 * [?] When picking up or  with a, the  will remain empty.
 *  [U]  An will not always point to the nearest  containing an . Probably occurs on maps generated with the debug  located at the coordinates (0, 0).
 * [X] If facing parallel to a line of wooden fencing with a gap that you intend to place a fence gate in, and you place the fence gate, the gate will not attach in parallel with the fencing but perpendicular to it. That is, rotated 90 degrees and disconnected to the adjacent fencing.
 * [X] A minecart with furnace does not push other minecart around, they just overlap
 * [X] The armor bar in the tool bar doesn't seem to show the correct amount of armor. A full suit of iron only fills up 8 1/2 points of armor and as the armor degrades the bar does not go down.
 * [X] With a small render distance, while in a hole with high sides, the sky is dark from the fog.

Graphical

 * [X] While in front 3rd person view under the effects of a, the swirls are not visible around the.
 * [X] items don't have the glowing effect in unlit areas.
 * [X] When in mode, the camera can be placed inside a wall, and works as an X-ray.
 * [X] Edges of blocks visible like in versions. Tested on.
 *  [F]  Holding an item turns the hotbar transparent.
 * [?] Cracking effect disappears when facing the block directly down.

Lighting

 * [X] s, s, and other objects have lighting issues dependent on the angle from which they are viewed, sometimes appearing black.
 * [X] s between two full blocks are dark when placed along the Z-axis. They are properly lit when placed along the X-axis.
 * [X] When are wet, they turn black.
 * [X] When swimming in, the background flashes from sky blue to pitch black.
 * [X] All light sources surrounded/encased by blocks appear to not give off light while smooth lighting mode is turned ON.
 * [X] s appear black when placed under a block.
 * [X] Underwater areas will stay lit up even after light source is removed or destroyed.
 *  [F]  The cut into Stairs,  Stairs, and  Stairs is not rendered properly.
 * [?] Black and white flickering when playing on Windows XP.
 * [?] s are black, unless in lit areas. (Confirmed in and )

Maps

 * [X] Snow s seem to have large amounts of chunk errors or chunks that do not generate properly.
 * [X] When a new world is generated, can grow on  and.

s

 * [X]If you feed wolves wheat, they enter love mode but won't breed.
 * [X] If you hook an with a fishing line, it continually teleports away, then back, then away, giving the appearance of flying, but with the line still attached to him.
 * [X] If you strike an in, no hit animation (enemy turning red and is pushed back) is displayed. If you kill an  in , it will only fall over and disappear with no other animations.
 * [X] s will not run away from you if they are in when hit.
 * [X] Passive s eventually escape when penned in by fencing.
 * [X] Animals trapped entirely behind (full height to a roof) will somehow escape after a long enough period of time.
 * [X] Animals that are trapped anywhere will jump wildly, partially phasing through the ceiling. This can sometimes result in an escape.
 * [X] Animal s will only spawn on new generated blocks in an old map, which is not the case for hostiles.
 * [X] When it s and are present on the surface, instead of teleporting underground, they will often teleport to another location on the surface, sometimes repeating many times, causing the  to appear to be flying wildly (and presumably killing it a lot of the time, as it seems  affected continue to do this until death, but that's not confirmed).
 * [X] s (and normal s, but not as much) will climb when attempting to reach you at inappropriate times, causing them to "stick" to the ceiling. Visually they will appear to fall and then climb back up, but you cannot hit them in this state. If you walk over and hit the ceiling where they actually are, they will react normally and resume normal movement. This makes s significantly more difficult to deal with, since they hide behind the supports of the mines they frequent and will not come out unless you put yourself at risk.
 * [X] When, after you feed 2 animals and they breed, the baby animal and all other animals of the same type will follow the 2 original breeders.
 * [X] s can not be attacked in the lower part of their body in.
 * [X] When a looks at the, it moves its head down instead of up.
 *  [F]  When in, baby animals have the adult's model and sound effects rather than the smaller baby model. They still do not drop resources until they have become adults, but there is no visual change.
 * [?] s don't spawn in mode if one switches from peaceful difficulty to a  world.
 * [?] s spontaneously die due to passing into blocks (presumably).
 * [?] Untamed are despawning and never spawning again, making them very rare.
 *  [U]  Sometimes s spawn in daytime above ground in the sunlight.
 *  [U]  s will sometimes spawn in a well lit room.
 * [X] Hostile may act neutral when spawned inside of s.
 * [X] Spiders and Cavespiders are still hostile towards the player in Creative Mode in spite of the claims that all hostile will ignore the player in Creative. Endermen will also engage the player if looked at in Creative Mode.

Multiplayer Related

 * [!] Spawn gets reset every time the server is stopped resulting in a MCEdit to fix.
 * [X] s are taking random damage when touching walls or s. It looks as if they are "sinking" in them.
 * [X] can place blocks in otherwise illegal positions. For example, an  can pick up a  and later place it on a  block.
 * [X] When you log out with barely suffice headroom, you may find yourself logging into a different place (typically on top of your old location, but not always the case).
 * [X] items in your  in  "show through" the normal  of infinite blocks. Doesn't occur in Single Player.
 * [X] Falling into the while riding in a  will cause you to disconnect from the server.
 * [X] es fall off when the block they are placed on is in another chunk.
 *  [F]  [!] When you shut down a server, it does not wait for all data to be saved to disk. save-all does nothing. stop does not wait for data to be saved.
 *  [F]  [!] Some chunks will not save the changes. When you leave and then return the area will be back to its original state.
 *  [F]  [X] s are invisible.
 *  [F]  [X] The have a bugged animation when thrown.
 *  [F]  [?] When a server is closed certain chunks do not save changes, restarting achieves nothing, appears to be the same chunks every time that have problems, modifying the chunks using MCedit also achieves nothing - keeps reverting to a much earlier save.
 * [?] On a new made server map huge gaps are formed. They go from the sky until the void. At the other side you can see the landscape going on. It is looking like a giant square gap in the middle of the map, and you can jump into it, though you die. This is not the same as a chunk error.
 *  [U]  If you die, you respawn in the

Memory/CPU General

 *  [F]  [!] CPU usage is always 100% on server even without people playing.
 * [?] Appears to cause the FDIV on Pentium processors.

Sound

 * [X] There's no sound when opening and closing a.
 * [X] There's no longer any sound when placing a.
 * [X] Sometimes, when crossing an invisible but constant boundary, the sound seems to stutter and echo for a few seconds, along with a large dip in FPS. The boundary, presumably, is a region (256×256) border, but may just be a normal chunk (16×16) border.
 * [X] doesn't have sounds.
 * [?] The sound lags and distorts when you walk or do anything and play songs with your.
 * [X] Walking near an active Nether portal will sometimes spike the memory usage resulting in lag. Can be seen using the pie chart in the debug menu.

Weather

 *  [F]  [X] It sometimes s through the ceilings of buildings and through the ground into s.
 * [?] splash animation (?) is not visible on all blocks. Seems to be random.
 * [!] Snow spawning destroys most non-solid blocks such as redstone dust, minecart tracks, torches, plants and saplings.


 * [X] The Fall Distance variable does not get reset when a player steps into (Only tested with Fire Resistance Potions, may not be the case with others) and as a result, when stepping out of, the player takes fall damage equal to the distance downwards they traveled. (This is not absolute distance traveled downwards: this is sum total of all downward motion. As such, bobbing up and down on the surface of  will increment this value.) This also applies to s; the fireproof  is known to "drown" in.
