Minecraft Wiki:Issues/Beta 1.9pre1

A pre-release for Beta 1.9 has been recently released by Jeb. This page is for reporting bugs on the pre-release of the game.

= Bugs = ''' Use the Discussion page first before editing any onto this page. '''

Bugs can be confirmed by checking into the discussion page and make sure other people reply to your report and have the same problem. If you and other people are experiencing a supposed bug, it may be listed here but with a "(?)" label in front of it to state the occurrence may not be a bug.

Note: An increase in experience when jumping is NOT a bug, please stop reporting this.

Biomes

 * (?) A change in a Biome to a Swamp has an immediate change in grass, tree, vine, and water colors unlike normal Biome borders.

Files

 * For new maps, the MB size in the world file under the Singleplayer menu will not change, it will stay at 0 MB. For existing worlds, the size in MB will not change when exploring new areas.

Gameplay
Pressing space will increase your experience level.

Memory/CPU General

 * Excessive lag on new or existing worlds, even if new chunks are not being created and all graphical settings are set to Fast/Off. The lag is much worse on single-core CPU's, possibly due to the threading of chunk saving/loading. Possible memory leak.

Crashing

 * For some players, creating a new map will stop the process and the game will say "Switching Level", and shortly after closes Minecraft.

Sound

 * Chests will not produce any sound when opening or closing.
 * Endermen and Silverfish do not produce any sounds.
