Unlike bug #633424, I do not see any problem with gnome-system-monitor GUI refreshing. Playing movies and flash is also smooth. However, holding a key pressed or moving a mouse does improve OpenGL performance as in bug #633424. And now the weird part: I have noticed that running google Chrome with google mail loaded also makes OpenGL smooth (I have checked couple of other websites but got this effect only with google mail).
