--- Comment #29 from lei.pero@gmail.com --- Just want to add few things, did reported bug to gnome project, but, problem does not happen when "vblank_mode" value in .drirc configuration file is set to 1 (instead of 0 I've used before).
Thought it would be nice to inform you about that since .drirc configuration belongs here, still could be mutter/clutter problem tho.
