Ok. Since you were mentioning XFCE and Display compositing" is its default that was my first idea. Unfortunately driver regressions are always possible and the older the hardware the more unlikely it is, that these get fixed again. :-( You may want to give Mesa's environment variable a try
LIBGL_ALWAYS_SOFTWARE=true
Well, I didn't even know that XFCE's window manager does compositing. You're right, it's the default, but I didn't notice it because it doesn't do any Compiz-like trick. However, I enabled some transparency in window handling, and I noticed that xfwm4 uses openGL indeed, but it runs very smoothly and without any gliches. Then I tried glxgears, which also ran with high FPS and without any problem, even when xfwm4 made it transparent. So 3D rendering is not entirely broken, only some functions of it, and the problem seems not to be in the kernel. The attached gmail glitch for example also occurs with windows compositing disabled. I'm afraid it's an upstream bug either in the X server or in Mesa. Thank you for the informations. -- You are receiving this mail because: You are on the CC list for the bug.
