Please attach (as opposed to paste) the full xorg.conf and Xorg.0.log files.

Sorry about the phenomenal bug spam, guys.  Adding xorg-team@ to the QA contact so bugs don't get lost in future.

This problem exists in the code released with Ubuntu 7.10.

I have seen scattered reports of this all around the net.  It seems that recent versions of Gimp use new XOR code that reveal a problem with the driver for ATI Radeon VE/7000 RV100 cards.

Please see https://bugs.launchpad.net/ubuntu/+source/gimp/+bug/156556

I will attach screenshot, conf, and logs.

I confirm the existence of this problem.

As of GNU Image Manipulation Program version 2.4.5 using:-

X.Org X Server 1.4.0.90
Release Date: 5 September 2007
X Protocol Version 11, Revision 0
Build Operating System: Linux Ubuntu
(xorg-server 2:1.4.1~git20080131-1ubuntu9.2)
Current Operating System: Linux imogen 2.6.24-18-generic #1 SMP Wed May 28 20:27:26 UTC 2008 i686

That's Kubuntu Hardy Heron fully updated as of 2008-06-17 this bug appears to have been fixed.

well, I just confirmed three hours ago that this problem still exists in my equally up-to-date ubuntu hardy install (which probably prompted you to look back here).  I assume, you just masked the problem by one of the various workarounds.

Reopening.

What exactly is the problem here?  Is it a particular tool in GIMP, or just GIMP in general?  Also can you attach your xorg log and config? Do any of the following options help?

Option "RenderAccel" "FALSE"
Option "AccelMethod" "EXA"
Option "AccelMethod" "XAA"

The various linked bug reports strongly suggest it only occurs when
using XAA.

  I think it may be related to composite.

  Try adding

Section "Extensions"
    Options "Composite" "disable"
EndSection

to xorg.conf

But the problem seems to be related to some ati cards.

https://bugs.launchpad.net/xserver-xorg-driver-ati/+bug/156556 should have all the necessary information.  Yes, it seems to be an ATI problem.  There are various workarounds.  Decreasing importance.

is this still an issue with a more recent driver/xserver version?

I am still on hardy, but comment 18 from https://bugs.launchpad.net/xserver-xorg-driver-ati/+bug/156556 confirms this to be still present in Intrepid.  xserver-xorg seems to be at version 1:7.4~5ubuntu3 in Intrepid.

Closing as WONTFIX; XAA is too far gone these days. If EXA does not work, file a new bug or attach yourself to an existing bug matching your issues.

For this particular bug, I'd say that re-opening is fine if it still happens with EXA.
