Opensuse 12.1
KDE 4.8 Release repository
Extra repository for KDE 4.8 release !
X11/Xorg repository for openSUSE 12.1 (anyway, same issue without this repo!)

Reproducible: Didn't try

Steps to Reproduce:
update from kde4.7.4 to kde4.8 (release repository). using opensource driver for ATI 9200 (on a notebook). with or without latest X11/Xorg packages from repository.

Actual Results:  
all window decorations are malformed. it seems, that symbols are oversized and font rendering is ugly (screenshot attached)

Expected Results:  
window decorations just should look like same as using Xrender (not opengl)

the window decorations have been rendering correctly using opengl before update to kde 4.8 !
though, i noticed this kind of issue occurs occasionally after update to a new version of KDE. After some weeks it seems to fixed, is it still the "old nabble" you can find on google ??? ([Bug 172627] New: Kwin composite not rendering properly with Ati free drivers)

the bug affects every kwin window decoration, independent from plasmas' graphicssystem (raster or default) !

here you can see the correct rendering of window decoration oxygen! don't care about the black color. the issue is the same when using default colors.
Comment 2 Thomas Lübking 2012-02-15 22:08:58 UTC
The black background is either configuration or inside the oxygen decoration.
The scale is the dupe.
