Using xf86-video-ati (Git), kernel 2.6.34 with Radeon KMS *disabled*, and KDE 4.4.3 results in graphical glitches like this:
The website that is rendered that way by Konqueror is http://www.nongnu.org/mingw-cross-env/#see-also (scroll up and down first to trigger the bug.)
This is only an example. It's not only Konqueror, but many other apps render garbage (Kate, drop-down lists in all apps, etc.)
This does not happen when using Qt's software renderer (-graphicssystem raster). Only when using the X11 renderer (-graphicssystem native). So for example to test it, start Konqueror with:
because it might be that your distro has configured Qt to default to the software renderer.
Can anyone confirm this? I had this with kernel 2.6.33 too, btw, but seeing that it's not fixed with 2.6.34, I guess no one knows about it.
Again: This is *only* with UMS. KMS does *not* have this problem.
