Desktop background redraw problem after minimizing window
Last modified: 2009-02-06 12:20:39 EST
Description of problem:
When KDE has been up and running for some time, minimizing a window does not
update the portion of the background that was occupied by the window (see
attached screenshot). This is independent of the application the window belongs
to. The only way to get the background back is to go change the background to
something else and change it back. I have Intel 865G integrated graphics running
at 1280x1024 on a 19" LCD display.
Version-Release number of selected component (if applicable):
Most of the time, once KDE has been up and running for some time and there are
at least 3 to 4 windows.
Steps to Reproduce:
1. Minimize the windows and check if the desktop background is alright

I can confirm this, I've seen it happen myself. Unfortunately, that's all I
know about this bug.
Hopefully, the KDE 4.1 updates that will be available soon will fix this
problem. I still don't see 4.0.99 in updates-testing. Does anyone know when 4.1
will be available via updates?

Thanks, is there a single group command with yum that I can use to get all of them?
yum --enablerepo=updates-testing update
I installed 4.0.99 and the problem seems to have almost resolved with it.
However, some times, when a large window or a maximized window is minimized with
many other windows also around, the screen stays garbled for usually 1-3 seconds
after which it becomes fine. So, I've never noticed it last.
The problem still exists with 4.1.0-3, but clicking once on the background redraws it and cleares all the mangling. So the mangling is no longer irreversible.
The problem is not i386-specific, I've seen it on x86_64 too.
What video hw/driver are you using? (My hunch is that it is a driver issue).
Oh, and are you using kwin/desktop-effects?
Nevermind, re-reading initial comment: Intel 845G
Fwiw, Intel 945G here, cannot reproduce.
I see it with Intel GM965.
And it isn't always reproducible, it only happens sometimes (but relatively often).
I'm using Intel 865G (In reply to comment #10)

I have Intel 865G integrated graphics.
No, I'm not using desktop-effects. Enabling desktop effects crashes my KDE and takes me back to the login screen.
I do see this problem on my laptop with Intel Mobile GM965/GL960 controller. I do not see it on my PC with nVidia GeForce 7300 LE.
