Specifically, I have been unable to get "The Witcher Enhanced Edition" to run without severely distorted video. I have both gnome and kde desktops on my system (kUbuntu jaunty-9.04). Today I tried running the game in gnome, and was surprised to find that it worked almost perfectly (the friend/foe rings still don't show up, but that's a minor issue).

Those problems go away if the "effects" in SystemSettings>Desktop>EnableDesktopEffects are turned off. This is a little surprising, because gnome also uses compositing effects, but I believe that gnome uses compiz, while kde has its own internal effects drivers. It's also odd that other games seem to work fine in kde with effects turned on; not at all sure why Witcher is different, but there it is.

It's a known issue. File a bug with KDE.
