NOTE: THIS MIGHT NOT BE AN XORG BUG, BUT A KDE / KDM BUG.

flickers. also goes black maybe 400 ms especially when scrolling opera
or firefox of scrolling with mouse in konsole. Going black does not
seem to be dependent on cpu load. It happens under light or heavy cpu
load.
Most annoying is that a 2 mm band that is maybe 2 cm long occurs
everytime I type, but the placement on the screen can occur anywhere in
the field of the web page in Opera (firefox also I believe). It is
always on the left edge, but random placement top to bottom. The band
appears to be black, and is more like 50 to 100 ms in duration.
/etc/X11/xorg.conf worthless for information
