Comment # 29 on bug 99418 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.
