I've been using bazzite for gaming + software dev for a few months now. I've decided to set up my Vive Pro setup to test out VR titles.
SteamVR home, and all other applications, have somewhat severe screen tearing. I also noticed a few other things like my main monitor turning black when starting SteamVR, SteamVR throwing an error when the headset sleeps occasionally, and some audio issues in Half-Life: Alyx. (Gunshots and voice lines not playing)
Happy to provide any further info, just ping me!
Edit: Tested on a windows install and its fine, just to confirm there is no issue with my hardware.
