How to reproduce:
- Have two simple levels. Literally does not matter what is contained in the level.
- Have the first level navigate to the second level at any point with “Open Level”.
- Open game in Standalone window. Or package your game and open it.
- You should see the screen become huge and unusable. The screen no longer fits inside your game window.
Step 4 should not result in oversized screen that becomes unresponsive.
I was able to reproduce this in a minimal project. Seems like a project breaking bug.
UE4 version: 4.25.2
BP used to change to Second Level
Second Level (Just a copy of First Level with BP code removed.)
