http://bugs.freedesktop.org/show_bug.cgi?id=14474 Summary: Screen artifacts on task switching and other wide- ranging screen updates Product: xorg Version: git Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Driver/radeonhd AssignedTo: lverhaegen@suse.de ReportedBy: wasti.redl@gmx.net QAContact: xorg-team@lists.x.org Created an attachment (id=14292) --> (http://bugs.freedesktop.org/attachment.cgi?id=14292) xorg log I have a R516 with two 1280x1024 LCDs connected. On task switching, visual artifacts appear for a split second on either or both of the screens. These artifacts are either other areas of the framebuffer or horizontal, black or white lines at a random vertical position. These lines, a few pixels high, push down the entire remaining content of the screen for the split second they exist, causing flickering. This happens only when hardware acceleration (either XAA or EXA) is enabled. Card PnPID is 7187:174B:3000.
