I suspect it's an issue with fglrx and its interaction with KDE.
I am also seeing this issue with KDE 4.6, Fedora 15, Catalyst 11.4 and a HD 5850 running World of Warcraft. When I run it fullscreen and switch to a different virtual desktop, the last frame WoW drew on the screen appears on top of everything else.
Switching in a GTX 460 and NVIDIA driver 270.41.06, everything works fine.
I also experienced the problem on World of Warcraft which is installed on my Windows partition and started with wine and the WoW "-opengl" commandline option.
Playing works flawlessly for a while and even switching Desktops and Alt+Tab works when suddenly wine seems to take over the GPU and either WoW is in permanent fullscreen and no alt+tab is possible or WoW draws the ingame Mouse cursor on my desktop.
When this happens i sometimes am able to switch with strg+alt+F1 to a console and kill wine but sometimes all input seems to be redirected to the game or is completely ignored.
