Works out of the box and has no stability / disconnection issues. Valve Index.
There were only old reports of the game (2+ years), so I reinstalled from scratch with Proton 6.3-5. No issues at all, besides the braindead control scheme of this game (which is the same as on Windows). No controller disconnection, no flickering, no crashes.

Regular controller desyncs. Not critical but annoying.
Game crashed after ~30min of playing
If after starting the game the screen is black but you hear the game sound then this means that you are outside your gaming area. Go into it and the screen will show up. This seems to be a feature as it is reported in the game's log.
Needs Proton 4.2-9 and working around some bugs. Long pause on first run.
Textures didn't load properly until I changed detail settings, then changed them back.
Game crashes with latest Proton, forcing it to 4.2-9 worked fine.
If you open the SteamVR interface, the game permanently loses tracking on the controllers. You have to quit the game and run it again.

The first time you run it, you'll see the EULA on your headset but then it will all just go black. After killing it and reloading it all worked fine. It is slow to load though with no loading screen on the HMD so be patient.

some month ago it didn't work. now it works great without any tweaks

After the EULA it can freeze for over a minute, but once it starts it runs well.
