KDE windows in Gnome open fullscreen when Maximus and Compiz are running

[Jakob Malm]

When running a KDE app (korganizer, konqueror, systemsettings tested) in Gnome with maximus and compiz running, the window opens in fullscreen mode, covering the panel. It should rather just display maximized, without window decorations, as is the case with Gnome apps.

With metacity running instead of compiz this problem is not present.

(Netbook-launcher is not running in either case.)

Thanks for reporting this bug. Some questions:
1. Which Ubuntu version are you running on?
2. Does this happen to all KDE apps or just a few?

Maximus only set's the "maximise" hint on a window, so it appears to be some break down in communication between kde apps and compiz...

Hi,

1. I'm running Ubuntu 8.10 on an Acer Aspire One. KDE 4.2 (beta, I suppose) was installed from Kubuntu experimental repositories.
2. Trying a number of different applications, it seems only the KDE-apps that I have used when logged into KDE are problematic, i.e. korganizer, konqueror, kjots, systemsettings.

I logged back into KDE, opened up those same apps, finding nothing strange in their behaviour, then went back to Gnome, and the problem seemed to be gone. Doing this a few times I got different results, and then I realized maximus gets started in in KDE as well...

Anyway, it seems that apps which just start one window (no tips or anything, e.g. konqueror, korganizer, k) start up the first time (including under KDE) just maximised. Second (counting also opening in KDE) and subsequent times the window opens over the whole screen in Gnome with Compiz on.

Do the KDE apps set some flag in the apps themselves to show up fullscreen when Maximus sets the "maximise" hint? That, I guess, could cause the described effect.

it also happens to me on firefox, even after i removed maximus...im on gnome...
any ideas?
Workarround: press F11 twice

I have the same issue here with kontact from kde 4.2 and gnome. There is no window decoration. Konqueror has a window decoration but no menu bar. I am using ubuntu 8.10 at the moment.

[Neil J. Patel (njpatel)]

I think this is a compiz bug, rather than a maximus one. Maximus only asks the window manager to maximise the window, it seems like compiz is doing something wrong with that hint on Qt windows.

Maybe add Compiz to this bug report?

[Thomas (thomas-scheffler)]

I don't know if I understand the report right. I do not have maximus running installed, but kontact 4.2 is running fullscreen and without window decoration. Is that the same problem or should I open a new bug?

[Jakob Malm (malmjakob)]

I upgraded to Jaunty alpha 6, and don't experience this problem any more. (Still with both compiz and maximus running.)

[Luis Diaz (diazluis)]

@thomas, had you installed netbook-remix or something related?
had you used maximus before?

[Thomas (thomas-scheffler)]

No I did not use any of these but after upgrading to jaunty beta my problem disappeared.

This bug has been moved to Ubuntu distribution.

[Marcin (marcinsud)]

On ubuntu 9.10 amd64 Gnome 2.27 and KDE 4.3.1 this bug affecting me. When I delete ~/.kde apps running good but I loose my settings

[Paul Larson (pwlars)]

Could someone seeing this on the current development release (karmic) please answer a few things:
1. Do you only see this with compiz enabled?
2. Does it only happen with certain kde apps (if so, please list some of them), or all kde apps
3. Please post a screenshot.

Thanks!

this doesn't seem to happen when "Legacy Fullscreen Support" is DISABLED in CCSM.. sadly this breaks other stuff (like MythTV)

[vjrj (vjrj)]

Paul:
I respond your questions:
1. yes
2. I only see this in kontact.
3. Attached

I'm using karmic.

[vjrj (vjrj)]

Update:
2. Also I see the same problem with konsole (but I can exit from Full Screen with keyboard or menu), k3b, but no with amarok (I'm using amarok 1.4, not amarok 2).

[Portable-Jim (christian-chess-geek)]

I have the same problem and the solution by ian_hawdon of disabling "Legacy Fullscreen Support" seems to work for me.

[Expired for maximus (Ubuntu) because there has been no activity for 60 days.]

[Michael Kogan (michael-kogan)]

Arch Linux, Compiz 0.8.6, no Maximus installed (whatever it is). Problem appears with K3b and KmPlot, the fix from the comment #13 solves the problem.
