driver bug, to workaround either really suspend compositing before going
fullscreen (shift+alt+f12) or disable suspension for fullscreen window (yes,
sounds weird ;-) in "kcmshell4 kwincompositing" (3rd tab)

*** This bug has been marked as a duplicate of bug 252817 ***

Please notice that not suspending fullscreen windows can have a major 
performance impact for fast updating clients (games, videos) by causing some 
overhead on the GPU + CPU - especially on the OpenGL compositing backend.
