Camera issue on Vive Focus Plus

[LeRuf]

Hello,

 

Trying to integrate a "passthrough" feature that will emulate the passthrough feature accessed by the double tap on power button on the Vive Focus Plus, so I can use the image to setup the virtual environment for my users.
However, we're running into a problem : when the application is launched, if the headset enters power saving mode and the application is paused, the camera doesn't work and update anymore.

Unity version is 2018.3.0f2, WaveSDK version is 3.1.94.
If anyone has a bit more stability with their camera usage in their application, I would love to know how you made it.
