Use xawtv to display a TV picture. Place mouse cursor in the TV picture. Press a key to change TV channel. Move cursor. 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 xfree86 as well, so that David can fix it (since he's the current driver maintainer)?
ping?
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. Parallelization. ;o)
