Today I noticed that instead of my screensaver only black color was shown. The screensaver was a hack noof from XScreenSaver. I bisected the commits and the one causing the problem was: ac8fdbc1c723afb19eeaba5457ba78d0bf33b8d4 st-api: Rework how drawables are invalidated v3. I also went through all the OpenGL XScreeenSaver hacks and noticed that 3 of them are affected by the same problem: cubestorm, noof and pipes. The hardware I'm using is AMD Radeon HD 5750 with r600g driver.
Thomas, any ideas?
This is fixed in latest mesa from git
