Please test against upstream components before filing a distribution bug upstream. That's excellent news. Is there an existing bug or even commit you can point me to? Obviously I would not have logged this if I could find the same bug logged already. Just the Ubuntu gfx stack is notoriously old, and since you have only tested against that stack you have not yet confirmed whether this is an upstream bug. In particular if you look at this, this is memory corruption that looks very similar to one of the many faces of bug 50019. I keep getting different Xorg crashes from Ubuntu 12.04 so can't get log files for this yet. On 12.10 with much newer intel drivers and similar hardware, I can't crash it any more. |

In Compiz, 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.
