Hello I recently updated from
1.0.999.494 to 1.0.999.508 on the VIVE XR Elite.
I am using the VIVE OpenXR Plugin version 2.0.0.
Then based on Richard Révész's post, I tested Vulkan and OpenGLES3.
When using Vulkan all I see is black in the headset.
When using OpenGLES3 I can use the apps as normal.
Since I had auto update on it took quite a long time to figure out what had changed. (Headset state after shipping it, Unity related, or XR Elite based). I guess I will turn off auto update on our groups demonstration headsets.
I confirmed the behavior above on multiple headsets.
