Title: Xorg crashes in drm_intel_bo_is_reusable() from intel_set_pixmap_bo() Status in Compiz: Triaged Status in “libdrm” package in Ubuntu: New Status in “xserver-xorg-video-intel” package in Ubuntu: New Bug description: re-redirecting an unredirected OpenGL window sometimes kills the X server. Test case: 1. Enable "Unredirect Fullscreen Windows" in CCSM > Composite. 2. Start an OpenGL game, or video with: mplayer -vo gl ... 3. Trigger scale (Shift+Alt+Up) or the window menu (Alt+Space) If it doesn't crash, then repeat. Expected: Either windows scale or the window menu appears Observed: Sometimes, just sometimes, X crashes and I get sent back to the login screen.
