This may be of interest to people using machines with (old?) intel graphics.

But someone then informed me that using "blt" instead of "uxa" not only fixed the text corruption problem but also significantly improved performance. I tried insert "blt" switched to mode 3, re-started X. I also ran tests using "gtkperf -c 200" before and after. The total time went down from 13.50 to 6.57, and I also felt that video performance after that was better (in browser and vlc).
