--- Comment #3 from Daniel shaddow2k@gmail.com --- I'm not sure if I and others experience the same problem as you, but when I try to start the first tutorial mission in DotA 2 (or change the resolution in the options menu), the game crashes. I reported my issues first at the Valve bugtracker: https://github.com/ValveSoftware/Dota-2/issues/597 https://github.com/ValveSoftware/Dota-2/issues/598
User dabreese00 compiled a collection of all similiar bug reports in the following meta-issue: https://github.com/ValveSoftware/Dota-2/issues/655
It seems to boil down to a general shader issue with Mesa, as users with Intel & R600 drivers are having the problems. When one delete certain shader files the game will start.
User Plagman there said "These GLSL shaders should be syntactically correct, so I suggest filing a bug against Mesa instead and using the official AMD driver until this is fixed on their end."
The latest version I did try was mesa/lib32-mesa 9.3.0_devel.57891-1.
I would really appreciate if you could take a look into the problem.
