Symptoms

Regression using Proton 5.0-7: SKYBOX VR Video Player works fine with Proton 4.11-13 but does not work with Proton 5.0-7.

When using Proton 5.0-7, nothing is shown on the HMD and on the computer monitor there is a fixed splash of the software:

You must have a Steam VR HMD connected in order for app to work correctly (in my case a Valve Index). I also noticed that without a HMD connected, the version 4.11-13 get stuck at the same splashscreen.

Here are the Proton's logs:

• Proton 4.11-13 (working): steam-721090-4.11-13.log
• Proton 5.0-7 (not working): steam-721090-5.0-7.log

Reproduction

1. Install SKYBOX VR Video Player
2. Force to use Proton 5.0-7 as specific Steam Play compatibility tool
3. Run SKYBOX VR Video Player with a Steam VR HMD connected

Start by reproducing SKYBOX VR Video Player with a Steam VR HMD, Proton 5.0-7, and the reported NVIDIA/Linux setup. Compare steam-721090-5.0-7.log with the working steam-721090-4.11-13.log to identify the regression; done means the application renders correctly in the HMD under Proton 5.0-7.
