GNOME Bugzilla – Bug 639853
loops with "Window manager warning: Log level 8: meta_shaped_texture_set_clip_region: assertion `META_IS_SHAPED_TEXTURE (stex)' failed"

How to reproduce:
1) run gnome-shell
2) go to espn3.com
3) pick some video to watch (warning: requires flash)
4) wait for it to start
5) full screen the video
6) switch to another workspace w/keyboard
The video un-fullscreens itself, and at that point, mutter starts throwing
Window manager warning: Log level 8: meta_shaped_texture_set_clip_region: assertion `META_IS_SHAPED_TEXTURE (stex)' failed
errors repeatedly in .xsession-errors.
It still runs, but system performance is greatly degraded because of the error loop. (Not to mention the log gets really large.)
Backtrace in gdb just shows it in the main loop.
This does not appear to be a 100% reproducer.
However, it's not limited to just ESPN3... fullscreen flash on youtube reproduces it as well.
