Serhiy, Florian emailed this to me in response to my pydev post on Linux gui tests. I'll let you decide if you think anything needs to be done.

FWIW, those tests seem to fail when using a tiling window manager

They however run fine in floating mode, so I'm guessing this is just a
limitation of those tests.

[serhiy-storchaka]

I already added a workaround to pass these tests on my netbook (new windows are opened maximized on it). May be there is a way to make a window floating in tiled window manager in Tk.

[The-Compiler]

At least with my WM, there is no concept of having floating windows when in tiling mode, so I don't think that would be possible.

I also don't think there's a standard way to tell a window manager to not tile windows.

What about opening a simple window with a fixed geometry, checking if this was changed by the WM, and if it is, skip those tests?
