Version: (using KDE 4.2.0) OS: Linux Installed from: Gentoo Packages In bug 178670 I was asked to report this as a new bug. So here it is: Because Plasma's transparance is not blured although kwin's blur plugin is enabled some rendering artifacts can be seen: Do this with KDE 4.2: 1. Set Plasma theme to Glassified 2. Set KWin's animation speed to very slow 3. Open Kickoff. -> You'll see some artifacts which are caused because plasma's transparence is not blured.
Please try and disable the fade plugin. I think you won't see these artifact any more in that case.
Yes, of course not. Should have added in my first post that the fade-in plugin must be enabled.
