https://bugs.freedesktop.org/show_bug.cgi?id=32789 Summary: VSync loss after rotation to portrait mode Product: Mesa Version: 7.9 Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/DRI/R600 AssignedTo: dri-devel@xxxxxxxxxxxxxxxxxxxxx ReportedBy: stapostol@xxxxxxxxx Created an attachment (id=41580) --> (https://bugs.freedesktop.org/attachment.cgi?id=41580) Xorg log file I have a monitor that can be rotated from landscape (1920x1080) to portrait mode (1080x1920) and vice versa. When I use the monitor in landscape mode, I can see a perfectly vsynced desktop. Once I move to portrait mode (xrandr -o left), the vsync is lost and scrolling or moving windows becomes a tearing fest. Compiz is running in both cases, with its "sync to vblank" setting enabled. (If I disable compiz, I get tearing in both landscape and portrait mode - even worse!) This is on Ubuntu 10.10: - 'uname' gives Linux 2.6.35-24-generic - 'glxinfo' gives OpenGL vendor string: Advanced Micro Devices, Inc. OpenGL renderer string: Mesa DRI R600 (RV770 9442) 20090101 TCL DRI2 OpenGL version string: 2.1 Mesa 7.9-devel My Xorg.0.log is attached. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
