--- Comment #5 from Stefan hybrid@onlinehome.de --- When bug 39953 occurs SC2 will create a crash log, for this one it does not. Also bug 39953 crashes the game completely as in the game window is getting closed and BLizzard's error reporter will pop up. None of these things happen when tampering with the shader settings, so to me it seems different.
