When will this get fixed and make the game playable? Windowed fullscreen with lower than screen resolution doesnt work and results in a too small window.

How to reproduce:

4k display
1920x1080 resolution
windowed fullscren

What happens?
1920x1080 window instead of stretched fullscreen windowed.

Fix or implement a proper fullscreen windowed mode, with different render resolution than screen resolution. Every modern game supports this.

The game still crashes btw if you switch ingame between windowed fullscreen and fullscreen...
