Created attachment 20092 [details] Xorg.0.log Forwarding this EXA bug from a Ubuntu tester: https://bugs.edge.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/291055 [Problem] Infrequent window decoration corruption under Compiz with EXA. [Original Report] I observe occasional corruption of window decorations. It is quite rare, though. It manifests itself as a tiny, horizontal, white line of garbage in the upper right corner of the affected window (on the decoration/frame, across the transparent shadow). The window decorator is the standard gtk-window-decorator that comes with Compiz on Ubuntu, with decorator setup at defaults and standard Human theme. I have no screenshot of this at the moment, because I am not sure how to reproduce it, but it does happen. I will attach a screenshot to this bug as soon as I see the problem. Xorg driver in use is xserver-xorg-video-radeon git20081003.f9826a56-0ubuntu2. EXA-acceleration is enabled. Ubuntu 8.10 (fully updated, installed from RC). Compiz is enabled. Human window decoration theme. Graphics card: ATI X1400 mobile radeon (R500), 128MB RAM. If more information is needed, please say so. I am also willing and able to test new GIT-snapshots of the radeon driver, and provide feedback if problems are fixed, etc. [Screenshot showing corruption] http://launchpadlibrarian.net/19122875/tiny-windeco-corruption-compiz-radeon.png [lspci] 01:00.0 VGA compatible controller [0300]: ATI Technologies Inc Radeon Mobility X1400 [1002:7145] Subsystem: Lenovo Device [17aa:202a] (See http://launchpadlibrarian.net/19073523/lspci-vvnn.txt for full output)
does: Option "AccelDFS" "False" or Option "RenderAccel" "False" help?
(In reply to comment #1) > does: > Option "AccelDFS" "False" > or > Option "RenderAccel" "False" > help? > I sincerely do not know :).. But seriously, I can try reproducing this one, but it's really hard, as it happens only very rarely. I have some vague memory that it has happened when stressing Compiz by opening lots and lots of windows. I might try that later. When I find some reliable way of reproducing, I can try the acceleration-options and see if disabling any of them helps.
