Setting resolution for windowed fullscreen

I am currently working on our games settings and changing resolution just does not seem to work correctly.

I am trying to use windowed fullscreen, because regular fullscreen was causing crashes when alt tabing, but no matter what resolution i put, it is always at 1920*1080. Tried using the command r.SetRes 1600x900wf directly in console and also the blueprint nodes for Set Screen resolution and Set Fullscreen mode.

I haven’t tested this in forever. But you needed to apply settings 2 times in blueprint.

How are you currently applying the changes?

After setting resolution and fullscreen mode i call apply settings. It works when i select windowed and sets the correct resolution there, problem is only with the windowed fullscreen.
