We really need a proper way to reproduce the problem, something that
leads to the crash other wise the chance that is gets fixes are null.

BTW, if you have a core dump, that's enough to get some information most
of the time. also you don't necessarily have to restart X if/when the WM

Do you see shadows under windows? Does the panel looks transparent? If
you can asnwer "yes" to this then you are running the composoting

*If* you are running the compositing manager, then it's a totally
different problem and KDE or GNOME don't include a compositing manager

Nope, the WM doesn't "negotiate" a size with the apps, but it can
eventually enforce it. It's what I am saying, I don't think it's
suitable to enforce a size.

Apart the crash (and taht's why I'm asking for more information), I see
nothing important...
