Is that an actual bug? Sounds like potentially a VRAM thermal issue.
You can see problems today like the mouse cursor not respecting Windows 10's night-shift color filter for the same reason.
This pointer not respecting night-shift hits the trifecta hat trick. There's a registry fix, of course, but the first time I saw it, I thought "huh, that's weird". How did this get out without somebody on the release train thinking to themselves the exact same thing?
