[Linux] Editor with multiple windows behave as if only one window was open

Hello,

When I open another window in the editor (e.g. when editing a blueprint), the editor behaves as if it was a singular window, not letting my alt-tabbing between them and other things. I have to minimize the blueprint window or move it out of the way to use the main window with the viewport, the child window somehow always draws on top despite the setting not being enabled in my DE. I also checked in my DE that I have no window rule that would conflict.

I don’t think that’s a normal behavior? Does anyone know how to fix that?
