Hello people. I have a problem. When use free video drivers x11-drivers/xf86-video-ati and compositing ON, X-server decreases when deploying windows from the tray. Always. When use closed video drivers compositing ON. Window disappear when they lose focus, and appears under the cursor.If compositing off, all work.
Trying to solve for a long time. Сhanged drivers.Cut off in turn effects.No results.
I have no doubt that the forum is my problem, but I understand very little english. And if you know where there is a solution let me know. Thanks

I use a KDE 4.5.3 Qt-4.7.1 Xorg-1.9.2 my card ATI HD 4650, system Calculate CLD 10.9 x86_64 AMD(aka Gentoo)

you should use the radeon driver if you want to use a free driver.

Both drivers do not work correctly. Or the problem is not vnih
Daily Update KDE to version 4.5.4 solved the problem
