As of 3.16-3 with Nvidia 396.54.09, there is a potentially similar problem (where the game stops drawing the screen buffer) in Job Simulator 2050 where the game screen buffer freezes after entering the dashboard. The dashboard is still responsive, but the VR experience is broken by seeing a still image in the game. Prior to stream output support, Job Simulator 2050 had a black screen, so this problem could not be observed.
I can reproduce this on Manjaro with Steam and SteamVR and Proton 3.16 (all betas) for Space Pirate Trainer. Can't test job simulator, as it seems to crash for me.
This happens for me in space pirate trainer, too.
There is no longer an issue with proton 4.11-2 and SteamVR beta 1.7.4. I don't know when it was fixed.

Your system information
Please describe your issue in as much detail as possible:
I expected to be able to resume playing Space Pirate Trainer. Instead, it refused to resume and if I recall correclty, I got a black screen. Coincidentally, if you open the dashboard while Space Pirate Trainer is loading, it will fail to load.
