Screen Resolution not working properly

Hello,

In screen resolution I set the resolution as shown in screenshots.

The problem is that r.setres 1920x1080w is working like r.setres 1920x1080f (fullscreen)
and r.setres 1280x720w is working like 1920x1080w.
What 's the issue?

I think you’ll find the modes relating to full screen only work in a packaged version.

( Possibly maybe stand alone, I can’t recall ).

Yeah for settings i run only in stand alone. Thanks for your answer
