Hi!
I am using KDE 4.2.0 on archlinux x64. whenever i want to watch a movie in dragonplayer or kaffeine4 (svn version) in fullscreen my screen goes black.
the same happens (sometimes) with vlc, although it's not so often with this player; I can't reproduce when it occurs with vlc. also i sometimes get a black screen when i open a terminal.
I'm using catalyst 9.2 (radeonhd doesn't support desktopeffects with my graphiccard, i don't want to miss them though)
does anyone else have this problem? is it a common video driver problem with x64?
