Stuck in fullscreen?

Hi,

I’ve recently migrated to 4.17 and noticed that my packaged game can no longer toggle between windowed and fullscreen using F11/Alt-Enter.

The command seems to run, because I see the window frame for like 1 frame then it instantly goes back to fullscreen again.

I tried using the console command to go to windowed mode and it works.

Seems to be the built-in toggle-command that’s behaving odd. Anyone else seeing this?

I had the same problem in UE 4.18.3 as well. I think the problem is that it doesn’t know which resolution to use. After changing the resolution once (see picture below), the problem went away for me.
