Description Bill Nottingham 2011-01-18 16:02:23 UTC
How to reproduce:

1) run gnome-shell
2) go to
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.
