https://bugs.freedesktop.org/show_bug.cgi?id=28383 Summary: Cloned screens with different res/refresh cause problems with mesa demos since new dri2 vsync. Product: Mesa Version: git Platform: x86 (IA32) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/DRI/R600 AssignedTo: dri-devel@xxxxxxxxxxxxxxxxxxxxx ReportedBy: lists@xxxxxxxxxxxxxxxxxxxxxxx I think this is linked to the new dri2 vsync but mat be wrong... rv670 mesa git, ddx git xorg git (2 weeks ago) drt kernels. Not just latest drt and unrelated to tiling patches. I am starting with a TV connected @ 1024x768 + vga monitor @ 1920x1080 so the top left section of the monitor screen gets tv(50Hz) vsync - monitor is 60Hz. If I start a mesa demo and it starts in the TV area it will sync to 50HZ if I move it outside the top left area it will sync to 60Hz. The problem is if I then move it back to the TV area it will stop rendering and become unresponsive. I can <ctrl><c> it but the window will remain. If I the move the window around enough I can get xserver to segfault. This doesn't happen with UMS or a drt from 29th April (uses old vsync). It doesn't happen if I disable TV with xrandr.
