When I draw a rubber band on the gnome desktop by drag the mouse on the left mouse button, I got ghost image of the rubber band left on the destop. The ghost image can fill up the rectangular area formed by the rubber band when I drag it slowly. It will disappear when foreground app covers it and forces the background to be redrawn. I am using Leadtek s320 which is a TNT based board running XFree 3.3.6 at 32bpp. It seems to me that it is TNT/32bpp and Gnome specific. I cannot reproduce it in KDE 16bpp, KDE 32bpp, Gnome 16bpp. Creative TNT/TNT2 also has similar problem. Other video cards do not exhibit this (at least on my notebook with Trident Cyber 9325 running at 24bpp/RH6.1). I have tried XFree 3.3.5 for RH6.1 also got this problem but it doesn't seem to happen on XFree3.3.3.1/RH6.0.
looks like a chipset problem, but not sure why other XOR operations don't produce the same symptom.
jonathan - is this a GMC problem?
It's more likely to be an X (or hardware) problem then a chipset problem. The only time I've ever seen gmc not do that correctly is when it's been a hardware issue.
I believe Preston meant a graphics chipset related issue, not a motherboard chipset issue.. I have seen a single time before that something like this occured in GNOME. It was totally unrepeatable and I never saw it since. I don't recall what video hardware I was using, but I am about 95% sure it was a Cirrus Logic 5446. Not sure which release of RHL/X it was either, but I believe it was 4.0.1 in 7.0. You say you're using a TNT card, and I know that they are not well supported in X, so this very well could be a driver problem. Can you please attach your X server log and your config file to the bug report using the link below? Also, if you have not upgraded to our released errata of XFree86 for Red Hat Linux 6.2, could you please do so, and update the report with wether or not it fixes the problem? The support for Nvidia hardware is, from what I understand, much better in the just released XFree86 4.1.0, however I do not have any NVidia hardware myself with which to test.
Closing bug report due to lack of response on issue, assuming fixed or user can't supply info anymore, or has changed video hardware.
