Created attachment 90859 [details] glitched control center I've been testing out gnome with the radeon drivers off and on, and have observed some graphical glitches with the window compositing. The easiest way I've found to produce a glitch is to use the gnome control center. Entering the "Displays" section, or entering any other section and going back results in a graphical glitch where something resembling the window appears to be composited over the top and left sides of the window. Triggering a repaint (by changing focus) gets rid of the corruption. Normally I use Intel integrated graphics, and I have not observed this glitch with them. Therefore, I suspect this is a problem with the Radeon driver, rather than mutter or gnome-shell. It may also be specific to radeonsi, as that is what I have (a Radeon 7870); I cannot confirm that it happens on any other Radeon drivers. I have, however, created a gnome bug, just in case: https://bugzilla.gnome.org/show_bug.cgi?id=720587 I believe I have also seen similar glitches involving Firefox and scrolling youtube videos toward the title bar. But I cannot reliably reproduce such glitches. I am using: Arch Linux kernel 3.12.5 mutter, gnome-shell, etc. 3.10 ati-dri from git, 2013-12-16 llvm from svn, 2013-12-16 xf86-video-ati 7.2.0 Radeon 7870 (pitcairn chipset) I'll attach some screenshots. Let me know if you'd like any other information.
