Does do_wait: drmWaitVBlank returned -1, IRQs don't seem to be working correctly. show up on STDERR when the problem occurs (the background changes) or before?
The warning comes from mesa, in http://cgit.freedesktop.org/mesa/mesa/tree/src/mesa/drivers/dri/common/vblank.c (in do_wait() around line 260). drmWaitVBlank() is in http://cgit.freedesktop.org/mesa/drm/tree/libdrm/xf86drm.c . ** Also affects: mesa (Ubuntu) Importance: Undecided Status: New ** Bug watch added: freedesktop.org Bugzilla #8722 https://bugs.freedesktop.org/show_bug.cgi?id=8722 -- Opengl is unstable with cairo-dock drmWaitVBlank returned -1 https://bugs.launchpad.net/bugs/428900 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
