Today i rebuilt Xorg modular from cvs and enabled mesa and dri.
Testing on my 9200SE, and almost everything is _very_ smooth. Xv works
now, it did not before when I was not loading glx and dri.
1. Resizing windows leaves some "garbage" in the area which was
2. Xv. Movie doesnt show when window isnt focused. forward/rewind in
xine mess up the picture.
3. launching glxgears seems to crash the server after a few seconds.
4. Scrolling in windows that contains text isnt very fast. ie kwrite,
konsole. Scrolling in konquereor is better, but i would not say
smooth. I only have anitaliased vera font, no core fonts anywhere.
5. Although moving windows is very smooth, I can see some tearing on
my tft monitor. By tearing I mean sort of the same affect as seen in
3D games when setting vsync off.
Thanks for your great work in "fixing" X :-)
