Pink/purple lighting with MediaVPs 4.7 and Intel Iris graphics

Thought I'd mention it, maybe helps someone.

I have an Intel NUC8i3BEH, has an integrated Intel Iris Plus 655 GPU. It's a low-power alternative to Intel's HD graphics in other CPUs. If Deferred Lighting is turned OFF, the light reflections on textures will have a pink/purple tint to them. Disabling specular lighting (-nospec) will fix the issue.

Game looks fine with these settings and runs at 120 FPS no problem.

Speaking of obsolete graphics cards, my Mac's Radeon 580 Pro 8 GB can't use shadows AT ALL - drops everything to 2 fps. I assume this is driver related (on Ventura patch from May 2025 so the drivers are in that) and I don't care much, but it case it helps.

It sounds like we don't have a GPU engineer atm... but if anyone wants to know I'm reporting it here. Since it seems appropriate. I know these boards get really low traffic so...
