Please attach your xorg log and config and dmesg output. Created attachment 48966 [details] [review] dmesg output Created attachment 48967 [details] [review] Xorg.log Created attachment 48968 [details] [review] xorg.conf Here they are. Please note that Gnome screencast (ctrl + alt + shift + r) does not record the issue. That's why I used my smartphone to record the video (and explain blurryness...beware it records at 25 fps on a 60 fps screen, frames can be blended by the recorder device) Do either of the following options help (put them in the device section of your xorg config)? Option "EnablePageFlip" "False" Option "ColorTiling" "True" Disabling EnablePageFlip indeed solves the issue. Is it a bug from page flipping or an "expected" behaviour ? It's a bug. Please try the latest 3.0 drm-fixes branch in Dave's kernel repo to see if it works any better: http://git.kernel.org/?p=linux/kernel/git/airlied/drm-2.6.git;a=shortlog;h=refs/heads/drm-fixes There are several pageflipping related fixes since 2.6.39. Specifically: http://git.kernel.org/?p=linux/kernel/git/airlied/drm-2.6.git;a=commitdiff;h=b7eff394670366a42935bfbaef67a6f7185627d7 http://git.kernel.org/?p=linux/kernel/git/airlied/drm-2.6.git;a=commitdiff;h=498c555f56a02ec1059bc150cde84411ba0ac010 Sorry for the delay (compiling a kernel is time consuming). I applied both patches to 2.6.39 kernel and it solved the issue. Thank. Are they going upstream in kernel 3.0 ? |

Created attachment 48943 [details] Picture of an artifact Hi There are some black shaped artifacts occuring over window on gnome-shell. I managed to record a video and extract an image displaying such an artifact. This bug is not deterministic, however it is very frequent : to make it appears, I only moved a terminal window on the bottom edge of the screen. Note that this bug is not specific to gnome-shell, it also appears on kwin effect in kde, and in others circumstance in gnome-shell, but the scenario described above is the easiest to reproduce. My hardware is AMD Zacate E350 (evergreen based), using Mesa 7.11 rc1 (bug is also in 7.10.x) on opensuse 11.4 64bits(is also on Fedora 15), with r600g drivers, libdrm 2.4.26 and ati ddx 14.2, kernel 2.6.39.
