Hello,
I have encountered a bug inside my unreal engine 5.4 project which I could reproduce in Fortnite too.
Reproduction steps:
- Launch the title and switch to Windowed mode in the settings
- Make sure the resolution is lower than the native screen/window size
- Move the title onto another screen
- Switch the window mode to Fullscreen
- Observe that the UI becomes unresponsive to mouse input
I could not reproduce this inside an unreal engine 4 project.
The issue seems to be related to a lower screen resolution. If the screen resolution matches the native screen size the issue does not appear. Switching to a lower resolution will cause the issue again.
My setup:
2x DELL S2721DS
NVIDIA GeForce RTX 3060 Ti
