Are you able to confirm some of the bugs/behaviors reported on this list with ATI/AMD? I am just curious if they are working on addressing for the next release?
Some of the examples that seem widespread include:
Slow scrolling, esp. in Firefox.
Slow FPS of compiz effects (maximize/minimize, cube rotate, etc.)
Corruption/screen artifacts over time, esp. surrounding the cursor
The three above seem widespread enough that they are not likely isolated configuration problems or specific to a board/chipset (as they have been reported from r300-r600 boards with a range of configs).
In general, compiz seems slower and more CPU intensive under AIGLX than it did under XGL. I know that when I was using XGL, I could drag a window around the screen and see virtually no hit to my CPU whereas under AIGLX I notice that a large portion of the CPU is dedicated to compiz effects. Are you able to confirm that ATI/AMD has delegated some of the AIGLX infrastructure to software instead of hardware rendering?
