Version: unknown (using 4.2.3 (KDE 4.2.3), Kubuntu packages) Compiler: cc OS: Linux (x86_64) release 2.6.28-11-generic I use the nvidia driver (maybe its important) and when I activate the effects "Blur" and "Shadow" at the same time there are some drawing errors on the screen. E.g. when I open up the K-menu and close it again then the region of the previous shadow leaves an wrong colored square on the window behind the K-menu. Sometimes it doesn't appear but I would say every second time here. I hope anyone can reproduce this... however, thanks for fixing ;-) Andreas
