It’s only a wild guess, though I have seen similar issues in other projects :), but I thought it might be worth reporting it to the developer in case it’s a just a bug. I love FOSS, it’s so satisfying being able to fix (some of) my own issues instead of having to hope that the closed source devs have time and motivation to fix it for you. SteamVR for Linux is one of those projects that feel like it could be so much better if they could open source it…
