PCVR - Black screen on PC

[RumarioVR]

Tested versions

• Reproducible in : Godot 4.5.dev5, Godot 4.5.beta1
• Not reproducible in : Godot 4.5.dev4

System information

Windows 11 - Godot 4.5.beta1 - Compatibility Renderer

Issue description

In PCVR mode, the Windows screen is black. The image in the VR headset is OK, but the PC screen remains black. Since I always record my VR videos with OBS, the image is important to me.

Steps to reproduce

Start Godot XR Tools Demo in PCVR Mode

I don't get the exact same behaviour but the colours or lighting are definitely wrong on the desktop view while being correct in the headset view. This is on an amd gpu (6800 xt) with 4.5 beta1.

I'd bisect it but I don't have godot builds set up on windows (it's probable that it occurs on linux too but the compat renderer doesn't work at all in xr on mesa).

Ah I see now this is probably a duplicate of #107655 and should be fixed by #107698

Indeed this should be a duplicate of #107655. Please let us know if it's still reproducible when 4.5-beta2 is released.
