[pygtk] After switching to fullscreen mirage gets decoration on blackbox

[petr.pisar at atlas.cz]

Hello,

I've met strange problem in mirage [http://mirageiv.berlios.de/] (pygtk
based image viewe) when I try to toggle the application into fullscreen.
The application gets fullscreen, but in short while it gets decorations
back. That should not happen. I'm using blackbox window manager
[http://blackboxwm.sourceforge.net/].

I've discussed the problem with developer of the application
[https://developer.berlios.de/bugs/?func=detailbug&bug_id=13532&group_id=66
37] and he thinks it's bug in blackbox.

The problem will not not occur if the full screen is activated from
maximized window. Also the problem will not prove in simple pygtk
application or if few descendant widgets are not hidden before switching
(discussed in mirages bug tracking system). It hapens in blackbox only.

I don't understand why some pygtk applications work and some other don't.

Any idea?
