Negative coordinates do not work on Linux(Gnome), but on Windows

[Thiago Milczarek Sayão]

Hi Dirk,

I have tried your example, it seems the window manager is denying the
application from being moved into negative coordinates, unless using the
window manager itself.

It might be due to security reasons, but that's just me wondering.

It might have a different behaviour on other window managers (modern gnome
uses mutter).
