Description of problem:
The root window is corrupted when using fast user switching on a R200.

Version-Release number of selected component (if applicable):
Whatever's on testday-20090909-x86_64

How reproducible:

Steps to Reproduce:
1. Use fast user switching (or attempt to a text mode console using Ctrl-Alt-Fn)
Actual results:
Root window colors are corrupted (and stay corrupted when you switch back and forth). Interestingly enough, only the displayed image is corrupt, a screenshot displays correctly after rebooting.

Expected results:
Root window is not corrupted

Running xgamma -gamma 1.0 fixes the colors (at least until the next time you attempt to switch VTs).

Despite how terrible this image is, the colors are basically accurate.

sounds to me like this could be the same basic issue as 522849...

xgamma reports values of 1.0 across the board while the colors are wrong, so unless the gamma fade is done without the knowledge of the X server, that probably isn't the problem.

hmm, I see. Thanks.

Since this bugzilla report was filed, there have been several major updates in various components of the Xorg system, which may have resolved this issue. Users who have experienced this problem are encouraged to upgrade their system to the latest version of their packages (at least F12Beta, but even better if the very latest versions).

Please, if you experience this problem on the up-to-date system, let us now in the comment for this bug, or whether the upgraded system works for you.

If you won't be able to reply in one month, I will have to close this bug as INSUFFICIENT_DATA. Thank you.
