Wrong aspect ratio on monitor in Unity6 URP and BRP

[elwes]

Steps to reproduce:

1. Install Unity6
2. Install with Package Manager SteamVR PlugIn 2.8.0 (sdk 2.0.10) · January 17, 2024
3. Main Menu -> Window -> SteamVR Input -> Generate Input
4. Open Sample Scene from: Assets/SteamVR/InteractionSystem/Samples/ -> Scene "Interactions_Example"

Everything looks right in VR but the image on the monitor is stretched and appears with wrong aspect ratio. It seems a vertically larger image is rendered and squeezed vertically. Tested it in Universal Render Pipeline and in Build in Render Pipeline.

I made a short video to showcase the issue: https://www.youtube.com/watch?v=-ORiF8pSpEM

Not sure how to fix it, I seems there is no way to change anything in Unitys settings for the camera, the resolution of the screen or otherwise. Would be great to get this fixed asap.

Can you try the beta version here and let me know if its fixed? https://github.com/ValveSoftware/steamvr_unity_plugin/releases/tag/2.8.3b2

I tried now:

1. Unity 6.1 (6000.1.2f1) with URP
2. SteamVR Unity Plugin - v2.8.3 (sdk 2.5.1)

First of all, it does not show an image in the VR Headset (Valve Index) and in Unity the VR-View does not move. Everything stuck in initial position. In the console I can see no errors.

Console output:

So, not much to see right now. The image, that is shown in the Game-View in Unity, seems not to be squeezed. But I would love to see all of this working, just to be shure it wont change once there is a tracked headsets and rendering in VR.
