MC-296750 fix
This fixes the startup crash on AMD GPUs with Linux.
This mod increases the minimum size of UBO offset alignment to a minimum 256 (or larger if your system asks for it), which is typical on Windows. On Mesa Linux, the minimum size is 4.
The unofficial word from Dinnerbone is:
Somewhere I must have a UBO be too small and it's being masked by the giant alignment rules on windows If you want to try to mod it better, there's a method in GLDevice that returns this value. Change it to 256 (or 8 or 16 or whatever, lower is better but 256 works for sure)
This mod does precisely that.
This gets the game to launch, and not crash, BUT there are severe rendering artifacts in-game.
