Bug#596061: xserver-xorg-video-radeon: display issues on kde4 when desktop effects are disabled (eg: window decoration not refreshed)

[fabienst at yahoo.fr]

retitle 596061 xserver-xorg-video-radeon: window manager display isses (kde4/kwin, but also lxde/openbox)

Actually, I noticed I have the same issue with LXDE/Openbox when opening the file manager, and then the terminal (LXTerminal)

Screenshot attached

Best Regards
Fabien

There is no xorg.conf on that setup.
