Re-enable Wine/Proton native window decorations

Hello, I wanted to ask if there is a way to re-enable the native decorations instead of using the builtin proton/wine ones. Their disabling is listed as a QOL change, but to me they’re more like a massive antifeature.

This is needed for fullscreen to work correctly AFAIK. To get a more detailed response please open an issue in the proton-cachyos github repository.

Strange, I’ve never had any problems with fullscreen. Not that I make use of it, since I run most games windowed, which is why this is a dealbreaker for me.
I’ll try asking on github for now, thank you for your time.
