Whatever it is called: It flickers :-)
Well, I have toyed around a bit more. Here is what I found:
- - It flickers woth the matroxfb_accel driver (and the unaccelerated version
thereof) from linux 2.2.16, 2.3.99pre5 and 2.4.0-test1-ac22.
- - The flickering is independent of the refresh rate of the screen. 60Hz is as
bad as 90Hz.
- - The flickering depends on the screen resolution! At 640x480 it is hard to
notice, at 1024x768 it awful.
- - The pageflip-demo shows exactly the same behaviour as berlin
I use a berlin with libart-DK which renders via GGI to the fbdev (on a Matrox
Millenium G200).
Any suggestions? I appreciate your help so far very much..
