Comment 24 for bug 270377

Hello,

The same here, I am using gnome, but also some qt4/kde4 applications. All the GTK apps work well, but skype, kmail and globally all qt4/kde4 apps seem to have redraw problems. It seems a simple click in the window triggers a redraw.

I have not tested it extensively, but it seems it disappears if I use metacity instead of compiz.

I also installed the whole kde4 desktop, and when I start a kde4 session, these problems seem to disapear (I use KWin in this case).

I tried combinations of compiz options --indirect-rendering and --loose-bindings without any success. I also tried the nvidia hacks suggested on some web sites (InitialPixmapPlacement, ect.) since I have a 8400GS card, but it does not solve the problem.

It is strange that so few people experience this problem.
