Description Martin Vogt 2008-10-21 11:02:07 UTC

Version:            (using KDE 4.1.2)
OS:                Linux
Installed from:    SuSE RPMs

Hello, 

currently I'm testing SuSE 11.1 Beta2 on thinclients. 

The thinclient does not support GLX/OpenGL most likely 
this is the cause of the problem. 

I will attach a screenshot of this bug, 
but its very similar to the bug: 

https://bugs.kde.org/show_bug.cgi?id=68878 

(reported 2003 ?) 

I dont have the artefacts when using a thinclient (remote X11) 
which supports GLX. 

regards, 

Martin 

PS: maybe its reproducible with a remote machine 
w/o GLX/opengl and

 X :1 -query <kde4host>

Looks almost identical to what is produced in the decoration preview widget on all machines. Could be related.

I can confirm that the bug is not in kwin/windowbar  when I use a thinclient
with GLX/OpenGL support.
(At least the bug has not yet shown up)

But it still is in the decoration preview.

Can you please check which decorations do and don't have this problem?

Hello,

I got the same Problem with Debian/Lenny on AMD64 with KDE-4.21 Packages from 
debian-desktop.org.

Problem only appears with NX, with Xming the Problem does not appear.

One year later, do you still see this problem?

>One year later, do you still see this problem?

Im still on SuSE 11.1 with KDE 4.1 <something> but the problem has
disappered.
(The decoration still flikers when changing the focus) but that was 
another bug report, so this problem is solved.
