1)Auxio, a great minimal one https://github.com/OxygenCobalt/Auxio

2. I use VLC mostly

3. Harmonoid, powerful and flexible and customisable https://github.com/harmonoid/harmonoid

Nvidia? Pop!_OS probably.

Mint is great but its using the legacy display manager so some people witg multi monitors with different frame rates bla bla had issued with it tho.

I checked this with youtube now and it pauses the video as soon as its in the background and I can play from notifications. Try updating too btw

Mine stop maybe because i have background battery restriction/autostart prevention. Not sure tho

Also mention lineage OS, Graphene OS and Calyx OS too

Its in notification with background play lol
