Screenshot illustrating the issue

After I upgraded the xf86-video-ati driver to the latest version 6.14.3 the screen image is garbled. Downgrading to 6.14.2 the screen image is ok.

My system is a HP Probook 6560b (Ati Radeon 6470M) Gentoo Linux, with kernel 3.1.0 (x86_64) and xorg-server 1.11.2.

Probably a duplicate of bug 33929.  Does xf86-video-ati git master fix the issue?

I don't know if this is a duplicate of the bug you say. I saw the screenshots posted there and the problem seems to be different. The strange thing is that kdm displays just fine, but after login and just before the plasma desktop is displayed, the screen is garbled the way I show in the screenshot.

What's the git repository to pull the latest code?

It depends what the apps are doing.  It could also be caused by an old version of mesa.  What version of mesa are you using?  Are you using the r600 gallium driver?

I managed to find some time and work on this issue. I enabled the gallium USE flag (Gentoo stuff), recompiled and activated gallium driver. I'm using mesa-7.11.1. I recompiled the ati driver and everything works just fine now! So, it was a software mis-configuration.

You can safely close this bug. Thanks for your time.
