mmh - after the last zypper up from the pontostroy-repository (containing
latest git stuff) I had the content of my windows upside down - the windows
itself were normal.

So I reverted from openSUSE factory to openSUSE 13.1 RC1 and also disabled the
pontostroy-repos. So I am back to kernel 3.11 and mesa 9.2.2 and glamor/opengl
2.0 on kde-compositing is still blazing fast, while raster is a bit faster than
native. There are even NO graphical glitches in both modes. Light games are
also working.

So another thing I have encountered in the past is that leftovers of fglrx
conflicted somehow with the system. How did you uninstall it - maybe that is
the problem. For instance I still have this leftover and I cannot find the
root:

grep fglrx /var/log/Xorg.0.log

[     6.628] (II) Unloading fglrx

this however does not make problems....
