Created attachment 319568 [details] broken KDE apps when maximized Description of problem: Only 2/3 of the screen is usable with the radeon driver. It starts with the login manager: With KDM the right 1/3 is garbage, with GDM the session box (GNOME, KDE, etc) is only half shown. After a login in KDE maximized windows looses some buttons in the upper right and sometimes the right half isn't visible (first screenshot). After a login in openbox the desktop wallpaper isn't set properly (second screenshot). If I use "vesa" everything is working fine. Also "nv" on another machine doesn't have this problems. I've tried some older drivers and it seems that the last working version was xorg-x11-drv-ati-6.9.0-15.fc10. With release 16 and above I'm getting these issues. Version-Release number of selected component (if applicable): xorg-x11-drv-ati-6.9.0-21.fc10 kernel-2.6.27-0.392.rc8.git7.fc10 How reproducible: ever Steps to Reproduce: 1. Update to xorg-x11-drv-ati-6.9.0-21.fc10 2. start X (esp. KDM) 3. login Actual results: The right 1/3 of the screen isn't really usuable Expected results: full screen area should be usuable. Additional info: I'm also one of the guys who have to use "nomodeset" at grub. So I cannot say if it's working with normal modesetting enabled.

I have the exact same problems. I should say that I use also mostly kde applications but in my testing the problems are not restricted to kde applications. Mozilla shows the same problems although in a lesser degree. There are applications that are more affected than others, konqueror is not affected, on other hand kmail is heavily affected. The rightmost part of the screen (roughly 1/3 as Sebastian says) is not drawn correctly if at all. My hardware profile is the following: http://www.smolts.org/client/show/pub_6824ca5e-57e4-4026-b764-c5dc475eb220 Taking the advice of Sebastian I can confirm that xorg-x11-drv-ati-6.9.0-15.fc10 works perfectly. When booting without the nomodeset option the same area of the screen is garbled when X freezes after leaving plymouth.
