[Runtime Bug]: GI Shifting in colour with NRC

Describe the bug

A bug happened where when using NRC if the room has very simple geometry with solid colour walls, the GI seems to shift in colour, possibly triggered by lighting changes from what the camera can see.

Encountered this while running gmod-rtx with the "Squid Game Full Facility | Games, corridors, basements, lobby & More" map

This doesn't seem to be a gmod RTX only issue since i encountered it in two other games a year or two back.

With cod-2 using remix entering a dim house only lit by outside and some lamps causes GI to shift colour depending on where im going.

With portal-rtx i remember when the energy ball exploded the entire scene gi shifted through the colour spectrum for 2-3 seconds before settling back to darkness.

How do you reproduce the bug?

reproducing seems to be inconsistent but the best idea i have is test it would be to find a very simple empty room with a blank colour (smth like beige or white) and have a moving light source, or just something that causes quick lighting changes in general

What is the expected behavior?

The runtime should have the GI's colour remain accurate to importance sampled

Version

The gmod-rtx runtime being used is based on dxvk-remix commit 6d75248

Start by reviewing nrc_session_log.txt, remix-dxvk.log, and the attached media, then try to reproduce the issue in a simple room with solid-colour walls and changing lighting while using NRC. Done means the GI colour remains accurate and stable instead of shifting during lighting or camera changes.
