Bug: Resize build's window while Unity XR Plug-in is initialised -> visual artefacts

For context.

We are working on a VR Standalone application that renders at the same time on the headset and the monitor. We have a custom camera rendering on the monitor, with UI a second user can interact with while the VR user has the headset on.

For the vrless user, we want the fullscreen mode to be "Windowed" and we have toggled "Resizable Window" on.

The issue.

After upgrading to the new Unity XR Plug-in management, resizing the build's window doesn't refresh the image inside the window, UI elements aren't selectable due to wrong positioning and there are visual artefacts everywhere if we minimize/maximize the window manually (dragging).

I've confirmed that the source of this issue is the new Unity XR Plug-in Management. Before the upgrade window resizing worked ok. It also works if we skip the VR initialisation and we have just the vrless version running.

Environment

Unity 2019.4.17f1
All packages are up to date via the Package Manager.
The same happens when we initialise either Oculus or OpenVR
Windows 10

Having the same issue with a similarly configured project. I'll let you know if I find any workaround.

 

Bump. Hitting this as well and would love to see a fix for 2020 LTS
