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.
Program received signal SIGSEGV, Segmentation fault.
