Description Romário Rios 2010-01-22 14:20:09 UTC 
Version:            (using Devel)
OS:                Linux
Installed from:    Compiled sources

I created a lateral panel to put some applications and set it to "Windows can cover" mode. It works fine the moment I set the config, but, when KDE is restarted, it acts like it was in the "Windows go below" mode.
Comment 1 Romário Rios 2010-01-22 14:25:06 UTC 
Something happened and these informations didn't get in the report:

Version: KDE SC 4.4 RC2 (a.k.a 4.3.95)
Installed from: Archlinux packages
OS: Linux
Comment 2 Beat Wolf 2010-01-22 19:16:46 UTC 
possibly a kwin bug
Comment 3 miguel.on.ito 2010-01-30 11:29:57 UTC 
I can confirm this problem. I have KDE 4.4 RC2 too.

oh crud, it happened again... but then went away when I tried to test it more. :/ maybe there's a race condition in there or something... yuck.
can someone else test this please?
Comment 7 Chani 2010-02-03 04:08:06 UTC 
damn. :( it's still there, but only when I'm not trying to debug it. :P

...now what on earth happened to the "new" status in bugzilla? guess I'll have to mark this "unconfirmed" even though it's not.
Comment 8 Cyril Brosch 2010-02-16 18:19:36 UTC 
I can confirm (KDE SC 4.4), but it happens in a very random way and never applies to all of my three panels.
Comment 9 rayunix 2010-02-18 17:35:05 UTC 
I confirm this bug in Kde 4.4 SC
my Distro is Kubuntu 9.10

Comment 11 Chani 2010-03-03 21:56:59 UTC 
_NET_WM_STATE_BELOW is definitely being set on these windows; I used xprop to
check. 
It's got to be a window management bug; plasma has set
keep-below (yes, *after* show()) and the message got through to X, so what more
can it do?
Comment 12 Chani 2010-03-03 21:58:59 UTC 
now let's see if I can fix the bugzilla assignee...
Comment 13 Chani 2010-03-04 01:57:42 UTC 
hrm. I did some general cleanup in panelview.cpp, and now I can't reproduce.
maybe it's magically fixed... maybe it's just playing hide-and-seek again.

anyone wanna try out trunk and see if they can still trigger it?

Comment 15 Cyril Brosch 2010-04-01 22:18:06 UTC 
Seems to be fixed in SC 4.4.2.

While it had been really annoying until yesterday, today I didn't have any problems. :-)
Comment 16 Chani 2010-04-02 21:57:45 UTC 
YES! :)

I still don't know how I fixed it... but at least it's fixed. :)
