Priority: medium Bug ID: 64738 Assignee: dri-devel@lists.freedesktop.org Summary: graphics corruption with glamor Severity: normal Classification: Unclassified OS: All Reporter: alexander@tsoy.me Hardware: Other Status: NEW Version: git Component: Drivers/Gallium/radeonsi Product: Mesa
I have these problems with Cape Verde Pro (HD 7750) card: 1. Graphics corruption when scrolling in gtk2/gtk3 apps (screenshot [1]) 2. Graphics corruption when moving windows in wm whithout compositing. Both gtk and qt apps are affected. No such artifacts when compositing enabled, e.g. in gnome 3. (screenshot [2]) 3. Missing notification icons of gtk2 apps in awesome wm.
All of this things works great whithout glamor. Also no such problems with HD 6450 card with both EXA and glamor acceleration.
Software: - mesa-9.2 from git - llvm-3.{3,4} from git - xorg-server-1.13.4, also tried 1.12* - xf86-video-ati-7.1.0 - glamor-0.5 - linux kernel 3.8* including latest 3.8.13
Also note, that with mesa-9.0* and mesa-9.1* Xorg segfaults at startup on this system when glamor enabled, but this is a subject for another bug report.
