I'm experiencing a strange issue here.
I've got
[Borderless Windowed Mode]
; Set to true to enable borderless fullscreen when the game is set to "windowed" mode.
Enabled = true
If the game is already in Fullscreen mode, I can change it to Windowed and the option works as intended.
However, after I save the Windowed option and exit/relaunch the game, my window will always appear like this:

The only way I can fix it, is to change back to Fullscreen mode before exiting the game, and then change it back to Windowed after relaunching.
And I have to do this every time between sessions.
If I try to change it to Fullscreen and back to Windowed while it looks like the screenshot above, it won't work.
Additional information, not sure if it could be useful:
- Two 1080p/60Hz monitors are in use, however only one is used for the game
- Windows 10 Pro, x64 version 22H2 (latest update version)
- Intel i7-4790K @ 4.0GHz
- GTX 1660 Super 6GB
- 32GB DDR3
