Description David Rees 2010-12-28 03:27:24 UTC

Description of problem:
Often when dragging windows, the display of the window is corrupted with the contents of other windows and the same window shifted around.

Version-Release number of selected component (if applicable):
xorg-x11-drv-ati-6.13.0-1.fc13.x86_64

How reproducible:
Frequently.

Steps to Reproduce:
1. Log in to X.
2. Notice that frequently the top menu bar has corruption as it slides down.
3. Every now and then dragging a window (all applications are affected), the contents will be corrupted with other parts of the screen.  Minimizing/restoring the window causes the window to be displayed correctly.
  
Additional info:
Will attach screenshot of corrupted terminal along with xorg log.

No xorg.conf is required to duplicate the issue.

Setting NoAccel to on or DRI to off solves the problem in my limited testing.

Seting DynamicPM to on seems to reduce the frequency of the occurance, but not completely in limited testing.

Sorry - not sure how I accidentally created this duplicate bug.  Think it happened when Bugzilla complained about the attachment I tried to attach from the bug creation page so I didn't realize that the bug was created, just the attachment was not attached.
