Problem with HoloLens background being drawn during capture in URP project

　I am developing a HoloLens application for the URP project.
　The app works fine on the actual device. However, when capturing, the background of the application is rendered black.
This is very similar to what happens when the Camera component is not set to SolidColor.
　I've tried this with other projects, but it always happens with URP projects.
　If you remove URP from the graphics settings and deploy as a normal project, the background will be transparent.
　It seems to be a setting around the camera rendering, but please let me know if there is anything I need to do in terms of settings or code.

〇Environment
・Unity2019.4(LTS) 、Unity2020.3(LTS)、Unity2021.1.10f1
・UniversalRP
・MRTKv2.7

 

I have the same issue, I have also confirmed it seems to only happen as soon as I implement URP. Any updates?

 

it seems to be resolved with the OpenXR lastest plugin (1.2.1) but the post FX glow or any transparency leads to very ugly black smears around objects.
If anyone have a solution to capture on Hololens with URP...

 

Would be curious also how to solve ugly black smears around objects in URP with the hololens
