Maybe some bug in the Linux version? E.g. if they’re receiving input events at a different rate than on Windows, and the code assumes it’s always the same… Just speculation but it feels like it wouldn’t be easy to draw anything if it was like this for everybody.
Man, you just don’t have this kind of insight anywhere outside of people into FOSS. Even with proprietary software ready to get into specifics and try to grok the issue. Kudos.
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…
