Description Siganderson 2011-07-12 11:35:45 UTC

Video Card: ATI Radeon HD 5670 512 MB RAM
OS: Kubuntu 11.04 32 bit
Software version: kernel 3.0 rcx and 2.6.38, drm git, mesa git, xf86-video-ati git, kde 4.6.4

ColorTiling can't be "true" (default) in xorg.conf otherwise all the programs that use opengl will have a very bad output (very jagged lines) full of distortions. This affects even kwin desktop effects.
As a workaround I put ColorTiling "false" in xorg.conf.

Please attach your xorg log, config, dmesg output, and glxinfo output.

Also, can you attach a picture of the problem?

I'm closing this bug, as I discoverd that it was my fault:
I noticed a /etc/ld.so.conf.d/GL.conf file that told kubuntu to load files in /usr/lib/mesa before /opt/xorg/lib (as I specified in /etc/ld.so.conf).
I discoverd this thing reading the output of glxinfo| grep Mesa that reported 7.10.2 instead of 7.12-devel...

I edited /etc/ld.so.conf.d/GL.conf in this way:
/opt/xorg/lib
#/usr/lib/mesa

and now things are working correctly.
