Bug 191250

Version:            (using KDE 4.2.2)
Installed from:    Ubuntu Packages

The menu appearing when I click on the cashew in the top right corner has graphics issues for me:
- When I open it, most of it sometimes have a brighter colour than it should have (there are some spots in which the right, darker colour is still displayed). This is a bit random in that it sometimes happens a sometimes doesn't when I click multiple times, but if it happens, it's always the same place (see screenshot - the darker part in the bottom right is the correct background colour).
- While moving my mouse over several entries, the background of items I leave is sometimes left in exactly the same bright colour. That is also random and does not depend on how quickly I move my mouse, and it's always a rectangle slightly bigger than the hover effect is.
It happens with both the Desktop and a Folder View as containment and no matter where I place the cashew (moving it changes the place in which the glitches appear though, but after being moved back they are at the old place again).

This is KDE 4.2.2 at Kubuntu 9.04, NVIdia GeForce 8500 with the 180.44 drivers from NVidia. It happens both with compositing enabled and disabled.
