Description Mike Whincup 2007-03-24 11:38:25 UTC

Installed from:    SuSE RPMs

Hello

After logging to KDE, window decorations are seen initially, and then, after a few seconds, the decorations disappear, with the following backtrace:

System configuration startup check disabled.

If I type...

kde-window-decorator --replace &

I can get the window decorations back, but they may disappear again sometime later in the session.

I haven't figured out how to recreate the problem.

I'm using Compiz, and SuperKaramba.

Thanks in advance...
Comment 1 Mike Whincup 2007-03-24 11:48:11 UTC
In the console window where I typed

kde-window-decorator --replace &

I occasionally get error/warning messages, e.g

~> X Error: BadWindow (invalid Window parameter) 3
  Major opcode:  20
  Minor opcode:  0
  Resource id:  0x3e00001
Comment 2 Lubos Lunak 2007-03-24 11:56:06 UTC
I probably want to complain to Compiz/KWD developers.
Comment 3 Ian 2007-05-16 19:36:44 UTC
This is the most frustrating bug I have encountered so far. I'm not a Linux expert by any means so any simple instructions on how to fix this would be greatly appreciated.
Comment 4 Lubos Lunak 2007-05-16 22:55:36 UTC
Sorry, that was supposed to be "You probably want to complain to Compiz/KWD developers", not I. KDE project does not develop KWD.
Comment 5 Philippe Devloo 2007-05-21 21:59:08 UTC
I had the same behaviour in mandriva 2007 spring edition
Comment 6 Brice Goglin 2007-08-09 09:24:24 UTC
Are we actually sure the bug is in kde-window-decorator and not in a KDE/QT library? This resolved/invalid status looks kind of fast and unexplained...
Comment 7 Lubos Lunak 2007-08-09 10:28:29 UTC
No, we are not sure. But we're also not sure it is in KDE/Qt. That's up to the KWD developers to find out and tell us if it's KDE/Qt problem.
Comment 8 Jyothi Swaroop Guntupalli 2007-08-10 17:34:50 UTC
So what's the solution now?? it says *resolved*!!
Comment 9 Lubos Lunak 2007-08-10 19:21:43 UTC
If it is a KDE/Qt problem after all, reopen and provide further information.
Comment 10 Mike Whincup 2007-08-12 00:23:49 UTC
Glad this thread hasn't died. If there is a resolution, I haven't heard of it...
I'll try to capture more details next time it happens.

It happens in AIGLX too.
I believe it's not a X's problem cause compiz runs fine in the same setup.

System here is:
Kubuntu 7.10 (amd64)
Athlon64 3500+
4GB RAM.
Video board: Nvidia 5700le 256MB

Comment 20 Sascha Hlusiak 2007-11-13 17:04:00 UTC
The last one is a crash because of the Crystal window decoration and not related to KDE or kwin. Crystal was made to embed in kwin and it's own feature "scroll windows on wheel" crashes with kwd running under it when you use the scroll wheel on the decoration. Please disable the feature in the kwin decoration settings dialog and see if it goes away.

This bug in Crystal IS ALREADY fixed, but Kubuntu seems to ship an old version of kwin-style-crystal (or whatever it is called). Please feel free to upgrade to 1.0.5.
Comment 21 Lubos Lunak 2007-11-13 17:34:22 UTC
As already mentioned in comment #4, there's really no need to add anything here. KWD is developed by Compiz developers and not by the KDE project. And, as said in https://bugzilla.novell.com/show_bug.cgi?id=304184, there should be already a fix somewhere.

Guys, 

I'm not sure whether to close this bug report now. 

Since I upgraded to Suse 10.3 (and have been running compiz) I don't think I've suffered this problem.

Lubos, what do you think?
Comment 27 bharatt 2008-01-09 21:22:50 UTC

Comment 29 Lubos Lunak 2008-01-09 21:49:06 UTC
This is not a KDE problem and it's been already fixed in Compiz.
Comment 30 David Todd 2008-01-15 20:56:12 UTC
I am using Mandriva 2008 with KDE and Compiz and I STILL regularly get this bug.  Usually it happens at first login but sometimes, like just now, it happens after i have been logged in for quite a while.  It is VERY irritating!

Lubos - I have faith that you know what you're talking about, and that the problem lies with Compiz or KWD.

I'm just not sure how best to proceed - Others have the same symptoms. Can you give me a link so I can map this problem to KWD?...
Comment 33 Lubos Lunak 2008-01-23 23:59:39 UTC
All I know is that in this Novell/SUSE bugreport I helped to fix the problem : https://bugzilla.novell.com/show_bug.cgi?id=304184 . But for Compiz problems you have to ask Compiz developers, sorry.

Running Mandriva 2008.0 with kernel 2.6.22.18

The kde-window-decorator crashed while rpmdrake finished successfully the installation of xine-faad package. This kind of crash is still very rare for me and this distribution apparently. 

Yet I attached my crash report on the comment above.

You should report this crash to the Compiz developers. Adding it here won't fix the issue. Btw you are not using emerald - the crash report says you are using kwd

Bug 232213 has a reference to the fix inside Compiz code for KDE4.4 code...

I do not think it is really a duplicate because:

1) I do not use compiz, I use kwin
2) The decorator crashes with segfault and restarts itself normally

Oh, and the platform is not at all OpenSUSE, it is kubuntu 1004 LTS.

From bug #264199:
"Application: KDE Window Decorator (kde4-window-decorator), signal: Segmentation
fault"

You /do/ use compiz - running kde4-window-decorator together with kwin would be completely pointless and wrong.
Also a crash in kde4-window-decorator while kwin is your windowmanager (or virtually everything bug compiz) wouldn't lead to anything onscreen, but the crashreport - which you could safely ignore since "running kde4-window-decorator together with kwin would be completely pointless and wrong" ;-P

Most important is that the _reported_ crash is a crash in kde4-window-decorator and therefore it is (for now) a "duplicate" - even if the traces don't match exactly (still it's "outside", the reason are likely incompatible API/ABI versions)
If you experience other crashes (which are really in kwin) you'll have to report them :)

Hi Thomas,

Thanks for coming back to me.

ps -ef | grep -i kwin 

reports kwin running, so does top (which actually shows xorg + kwin are consuming a vaste amount of resources).

compiz is not reported running.

Best,
What is going on here?
Comment 63 Thomas Lübking 2011-01-25 18:27:41 UTC
hard to say.
you probably ran compiz sometime in the past which successively launched kde4-window-decorator.

when you re-replaced compiz by kwin, the decorator was not shut down by compiz, stored with the session and restarted with every login (doing nothing but sucking some resources, it's not a window manager by its own but just a compiz "plugin", so there's no _real_ conflict with kwin)

at some point it then apparently crashed, but that should not have had any impact on kwin (the only result would be the crashdialog) - if there was really another issue (crash) with kwin in consequence it's not been in your report.

Thanks Thomas.

I think I will clean up the installation and see what happens.

I agree w eshould consider it as invalid at this stage.
