Using Iceweasel as my browser and the NASA Night Launch theme I'm seeing some image deformation in the area unoccupied by the scroll bar. Usually tiny black and gray boxes appear in that area, but now in latest git I see a series of jagged lines.

git-bisect reveals that the problem code is somewhere in this commit:

Thanks for all the hard work, radeon developers!

What chip are you using?  Please attach your xorg log.

Looks like it doesn't repeat the pattern (properly) but stretches it.

Can confirm the fix resolves my issue. Thanks for all your work!

This bug is certainly fixed on my desktop machine, but it apparently isn't on my laptop and I'm not sure why.

My laptop has pretty much the same chip as my desktop (Mobility HD 2600 -- rv630) and is at latest git as well. However the fix presented in ec1a3ccdf61c2226617b571cc4a209a542e9d7e3 doesn't seem to be working on it.

I've attempted to get kms/3d running on my laptop and as a result, I've compiled and installed off-distro programs. So I'm wondering if this could be the problem.

This bug was only present on git master. Make sure you are using the latest git master.  6.12-branch stable releases are not affected.  Also, KMS is not supported yet on r6xx/r7xx chips.

I believe I was on latest git master. To be certain however I did a fresh clone in a separate directory and built from there. And the bug is still present when I restart X.

I've also tried out my distro provided package which is at 6.12.2 (I did uninstall my git driver before doing so) and it's still there. I'm not sure what is going on here since the bug is fixed on my desktop. Is there something besides radeon that could be causing this behavior?

Sounds like the versions you've built are not actually being used.  By default the driver installs in /usr/local.  Make sure the correct driver is being used when you start X.  Also make sure you stop and start X rather than just logging out and back in.
Comment 12 Brian Paterni 2009-07-01 13:51:53 UTC
Yep, it turns I needed to remove a ModulePath from xorg.conf to prevent it from loading an old version of the driver.

Thanks for your time Alex, although it did turn out to be human error in the end.
