Minecraft has severe graphics glitches (diagonally split view on the minecraft window, half the image of the background and half minecraft.) it flashes sometimes..

I don't know if that is relevant but I read something on the openGL documentation about graphic images not being dividable by 4 or something, which causes the diagonal corruption of the final image.

So. I tested minecraft in Ubuntu 12 beta 2 (64bit) which did not have that graphical error.

I upgraded the kernel to the version Ubuntu 12 had (3.2), however same problem occurs.

I have Intel B800 processor, with intel hd graphics 2000 i presume. it doesn't tell on ark.intel.com website. Using lspci -v outputs

00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) (prog-if 00 [VGA controller])

When minecraft is open, the ubuntu interface also lags, like text etc, buttons also split diagonally in half... Its weird.

So you have both systems on the same computer? why don't you just wait those 8 days that are left until 12.04 gets final, and then you use 12.04? –  jP_wanN Apr 18 '12 at 20:41
    
Thought about waiting.. but the answer to the question is bugging me. –  matejkramny Apr 18 '12 at 21:18
