Some applications behave differently at a different screen resolution. Is there any way to get the system to report a different, user-specified, resolution to a GUI application when starting it?
By behave differently I mean for example their unresizable window is smaller (not necessarily physically, for obvious reasons, but fewer pixels) if I first switched the monitor to a lower resolution.

Or is there any method to force-resize unresizable windows?
