--- Comment #6 from Anastasius Focht focht@gmx.net --- Hello folks,
--- quote --- Matteo claims he has seen this problem with ARB too. Not sure if it's really exclusive to GLSL. --- quote ---
I've now done more than 1100 battles (~275 hours of gameplay) and never seen a problem with ARB shaders. Its very likely related to GLSL shader backend.
By having a large number of consecutive games I found another issue though, a GL memory leak. I'll create a separate bug for it.
I've also extensively used CSMT from Staging tree and it doesn't make any difference - besides doubling the framerate ;-)
Regards
