I finally compiled KDE from Ubuntu sources (apt-get source -b
kdebase-workspace) with the XSync based paint defer activated (I deleted the
#if 0...#endif) and I can confirm Tommaso's results: the problem persists.

Also, I've been investigating and I'm afraid I made some mistakes. It really
seems that I had been using XRender with my development user.


This is the output of "kwin --replace" in my normal user (both vanilla KWin and
Ubuntu's KWin):

And this is the output with my development user (Ubuntu's KWin):

OpenGL vendor string:                   Advanced Micro Devices, Inc.

kwin(8822) KWin::Workspace::setupCompositing: KWin has detected that your
OpenGL library is unsafe to use, falling back to XRender. 
kwin(8822): Failed to initialize compositing, compositing disabled 
kwin(8822): Consult
http://techbase.kde.org/Projects/KWin/4.0-release-notes#Setting_up 

(With vanilla KWin it changes to:

Direct rendering:                       no
Requires strict binding:                no
GLSL shaders:                           no)

In fact, using KDiff3 I can confirm that there are no differences in KWin
between vanilla and Ubuntu sources.

I don't know why I can't activate direct rendering with my development user but
the fact is that, unfortunately, the XSync based paint defer doesn't resolve
the problem. Sorry for misleading you.

Is there anything else that I could try?
