I haven't seen this, nor do I know what's going on, but here are some
things I would check if I were seeing that sort of video breakage:

Thanks for responding. I was wondering if everyone had kill-filed me.

Do you have compositing enabled (under Window Manager Tweaks)? If you
do, does the problem go away if you disable compositing?

Compositing is not enabled, according to the GUI. Maybe I should try enabling it. (My son's monopolizing the box right now.)

Hmm. I enabled compositing and, while the blit leftovers don't immediately go away, sometimes, but not always, several seconds after they appear, they go away.

I'm assuming that you're using more or less standard Xfce.

Haven't been ambitious enough to do a lot of modding, so it should be. But I'm not confident I got all the implicit dependencies taken care of when I upgraded from squeeze to wheezy.

If that's
incorrect, a more detailed description of your desktop setup would be
helpful.

And do you know what video card you're using and what driver?

On-board graphics on a cheap AMD (Sempron) motherboard -- VIA KM266pro, I think, maybe KM400, + VT8237 -- from about eight or nine years ago.

From "lspci -nn | grep VGA" :

01:00.0 VGA compatible controller [0300]: VIA Technologies, Inc. KM400/KN400/P4M800 [S3 UniChrome] [1106:7205] (rev 01)

I guess this is the appropriate comment on the state of the driver:

http://packages.debian.org/wheezy/xserver-xorg-video-openchrome

--- hardware acceleration has been ripped out of the sourceforge code.

Which sounds like some NPE went after the project.

And makes sense, seeing as the problem appears to be delayed video refresh.

I think I'm going to put up an IP honeypot for NPEs and start sending the FBI complaints about fraud and racketeering. (Take a while to plan.) Troll is too nice a word for them, we need to start calling them what they are.

Again, I'll have to get my son to finish up what he's doing, to look at the dmesg and /proc carefully. A quick scan didn't find me the drivers and he wants to play with the internet.

regards,
mike

Thanks.
