Created attachment 122748 [details] kotor2-shadows-frame296.png (In reply to Nicolai H�hnle from comment #5) > almos, I'm surprised that you're not seeing the glitch. What's your system > setup and hardware? I attached the saved image of frame 296 (which contains call 1919333 mentioned in the original report) from the shadows trace. I don't see corruption on it, even though MSAA seems to be enabled in glretrace. My card is a R9 270x, and I have Mesa 11.1.2, LLVM 3.7.1.
