I don't know if this will help anyone, but I just tried using Steam "Add a Non Steam Game" option.
Browsed to executable and selected it.
Then chose properties of that item in the list, chose Compatibility and chose Proton (Specifically, I have Proton GE 7.20 that I've installed for other games I chose).
I launched it, ran through setup without issue.
The first launch, it is in an annoying, bordered window so you can't see much of the title-area.
- So, I clicked on the nib of the menu I could see, and changed skins to my favorite dark skin. It automatically restarts. Bang, borderless window as it should be.
- I notice there are some skins and the default skins that the border still appears around, but... I'm sure there are some config switches that could be used.
I've only been playing around with it for a few hours, but my radio stations work, all my files are fine (on "Z" drive) - I LOVE this.
NOTE: Once you've used it and closed it - you need to redo your shortcut so it doesn't keep trying to re-run the setup file:
Open your file manager
- Search your steam folder for 'musicbee'
- Locate the MusicBee.exe in the steam pfx directory similar to this:
--> "/home/username/.steam/debian-installation/steamapps/compatdata/2464933901/pfx/drive_c/users/steamuser/Desktop/MusicBee/MusicBee.exe"
- copy that location, then paste it into the 'TARGET' field of the steam properties, and then the same location (minus the filename itself) in the 'START IN' field.
Then, if you want to get creative / cure your OCD like I do... grab an icon and an image from somewhere, and dress up your launcher icon and backdrop
lol
So - just an option throwing it out there just in case.
Thank you again to MusicBee for my favorite player ever!
