Use xawtv to display a TV picture.
Place mouse cursor in the TV picture.
Press a key to change TV channel.
When I subsequently move the mouse, I get a black square in the picture where
the cursor was during the channel change. This is with i810 video and a
bt848-based TV card.
Can you test wether or not "swcursor" makes the problem go away, and then
report this upstream to email@example.com as well, so that David
can fix it (since he's the current driver maintainer)?
Defering for future
This is likely fixed in 4.3.0 in RHL 9 now, so I'm going to assume that, and
close it CURRENTRELEASE, however if the problem exists still in RHL 9,
please file a bug report upstream at http://bugs.xfree86.org and then reopen
this report, and add the upstream URL and I'll track it upstream.
