Hallo, last week, I installed Fedora 12 with radeonhd on my Fujitsu Siemens Amilo XI 2550. There are some graphic problems. Up to know, I used Catalyst (fglrx) under Fedora 9/10. Symptoms: 1. See screenshot-links. http://img534.imageshack.us/img534/7369/dolphin1a.jpg http://img714.imageshack.us/img714/7332/dolphin1b.jpg http://img51.imageshack.us/img51/3927/gwenview1a.jpg http://img714.imageshack.us/img714/4150/gwenview1b.jpg http://img51.imageshack.us/img51/8216/kmail1a.jpg http://img714.imageshack.us/img714/7288/kmail1b.jpg I made a screenshot of doplhin (dolphin-1a). Then, I opened gwenview and viewed some jpg's. After closing gwenview, the dolphin window was quite strange (dolphin-1b). I set up gimp to make a screenshot in 10 seconds. Then, I opened gwenview and displayed the flower in full size. When the 10 seconds were over, the screenshot was taken (gwenview-1a, I did not switch the screen). I switched to the gimp screen, and set up gimp to make another screenshot in 10 seconds. Then, I switched back to the gwenview screen and gwenview-1b was taken. The desert is a part of the background image. A similiar effect is shown in kmail-1a and kmail1b. This problem is reproducable, in particular when I display large images in gwenview in full size. 2. I use kslideshow when I lock the screen. kslideshow uses various effects when switching from one image to another. Sometimes, kslideshow changes randomly pixels when switching from one image to the next. This effect is extremely CPU-consuming. 3. Displaying webpages with flash-aninmations is very CPU-consuming (in comparison to flgrx under Fedora 9/10). Sometimes /usr/bin/X takes 30% CPU, but these 30% remain even when I close the browser. 4. When I turn desktop-effects on, everything is very slow. It becomes even slower when I use the Composition method OpenGL.
