Description Nineth 2008-07-23 06:11:11 EDT
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):

How reproducible:

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
Actual results:
See attached screenshot

Expected results:

I can confirm this, I've seen it happen myself. Unfortunately, that's all I 
know about this bug.
Comment 3 Nineth 2008-07-26 18:05:33 EDT
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?
Comment 6 Rex Dieter 2008-07-26 18:55:47 EDT
yum --enablerepo=updates-testing update
Comment 7 Nineth 2008-07-27 02:29:20 EDT
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. 
Comment 8 Nineth 2008-08-18 11:02:52 EDT
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.
Comment 9 Kevin Kofler 2008-08-18 11:08:18 EDT
The problem is not i386-specific, I've seen it on x86_64 too.
Comment 10 Rex Dieter 2008-08-18 11:11:00 EDT
What video hw/driver are you using?  (My hunch is that it is a driver issue).

Oh, and are you using kwin/desktop-effects?
Comment 11 Rex Dieter 2008-08-18 11:12:25 EDT
Nevermind, re-reading initial comment: Intel 845G

Fwiw, Intel 945G here, cannot reproduce.
Comment 12 Kevin Kofler 2008-08-18 11:15:48 EDT
I see it with Intel GM965.
Comment 13 Kevin Kofler 2008-08-18 11:16:37 EDT
And it isn't always reproducible, it only happens sometimes (but relatively often).
Comment 14 Nineth 2008-08-18 11:18:50 EDT
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.
Comment 15 Ralf Kleineisel 2008-09-15 12:08:03 EDT
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.

The information we've requested above is required in order to review this problem report further and diagnose or fix the issue if it is still present.  Since it has been thirty days or more since we first requested additional information, we're assuming the problem is either no longer present in the current Fedora release, or that there is no longer any interest in tracking the problem.

Setting status to "CLOSED: INSUFFICIENT_DATA".  If you still experience this problem after updating to our latest Fedora release and can provide the information previously requested, please feel free to reopen the bug report.

Thank you in advance.
