Description Tamás Németh 2009-05-07 09:58:04 UTC

Version:            (using KDE 4.2.2)
OS:                Linux
Installed from:    SuSE RPMs

When I start a KDE 4 application on compiz, then maximize it and the close it, when started next time, it will be fullscreen instead of maximized (no window decoration, occupying the whole desktop area and overlaying all other windows except the panel).

It only happens when the application's last run was under compiz. If I maximize it under kwin, then close it, then switch to compiz and start the application again, it will be displayed correctly. However, when I just close and start it again under compiz, then it becames fullscreen again.

This bug was already reported ( https://bugs.kde.org/show_bug.cgi?id=180771 ), but the closed as INVALID. Please don't close it now, because:

-It only hapenns to KDE4 applications, Firefox, OpenOffice, etc. is totally unaffected.

-Even other QT4 applications (e.g. skype) are unaffected.

-KDE3 applications are also unaffected.

-Allegedly KDE4 itself is also unaffected before 4.1.3.

Sorry, I was mistaken. To be more correct, kde 4 was allegedly unaffected before 4.1.2. 4.1.3 was OK. BTW, 4.2.3 is still affected by this problem.

Disable the "Legacy Fullscreen Support" in Compiz configuration and try again. It should solve this issue
Thanks

Yes, it solved the problem. Does anyone know the reasons behind? Is it a compiz or a KDE bug?

Comment 4 Dario Andres 2009-05-08 14:32:08 UTC

According to : https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/159664 this cause the bug in OpenOffice too.
Marking as INVALID as this seems to be a Compiz bug.
Thanks

No such problem for me. It really happened with very old compiz versions but not nowadays.

I've found the exact reason of this bug ( https://bugs.freedesktop.org/show_bug.cgi?id=19701 ). KDE windows may be sized too big. Maybe the KDE project can help to solve this problem, maybe not.

Comment 7 Dario Andres 2009-05-08 17:59:25 UTC

Have you tried with Qt4-only applications ? Thanks
