@CubeTheThird Thank you for giving me a possible solution almost 1 year after and in another bug report. However, i don't know why Minecraft developers didn't fix this bug since LWJGL is open source, they could pull a patch into the LWJGL git repository, Don't you?
@LukeRuggiero Thanks for confirming this bug. Have you a tremendous lag when you are playing Minecraft?
Added more descriptive game log with a lots of information
Now the new game log contains a sound error
Please, link to this bug which i reported almost 1 year ago and no developer reviewed it: MC-53549 . I think linux users are marginalized
Yes I do and i think i have a worse game performance.
Thank you.
Logs from the game and launcher. It seems the game are skipping ticks but only when i try to pause. The game log doesn't show anything when the game freezes or slows down. Also I added more memory to JVM in launcher options but i doesn't work.
Updated once again...
Currently i'm using Ubuntu 14.04 to play Minecraft 1.8 but the problem is still there.
I updated the affected versions and added more information.
Thank you.
If someone knows how to report this LWJGL issue on GitHub i appreciate it. If this is not a LWJGL issue, please make a research for fix this bug.
