Blender Version
Broken: 4.1.0, 40a5e739e2, blender-v4.1-release, 03-25-2024

Short description of error
Viewport: Material Preview cannot display correctly Principled BSDF material when any amount of Transmission (Weight) or Coat (Weight) is applied to an object on the scene. Same happens for Specular BSDF if you add any amount of Clear Coat.

Exact steps for others to reproduce the error
Launch Blender on default cube scene
Change Viewport Shading to Material Preview.
Go to Material Properties and with default material (Principled BSDF) add any amount of Transmission (Weight) and/or Coat (Weight).
Orbit around the scene, or move the cube.

Same happens for Specular BSDF material if you add any amount of Clear Coat.

Hi, thanks for the report. I doubt whether that commit is responsible, only tests are updated in that.

Hi. That commit is the only reference I have access to, it worked fine until the daily build released the day before.

I can add it seems to only affect Viewport: Material Preview, because the Viewport: Rendered works fine, it also renders ok

@Michael-Parkin-White-Apple hi, can you check?

Can't reproduce with 4.1.1 rc build

Still happening on latest 4.1.1 810bfcc30a RC build on my AMD FirePro D500 Mac Pro on Monterey 12.7.4 (21H1123)

Your Intel Machine is a Mac Pro Trashcan w/ Dxxx series AMD gpu @iss ? or is it another newer AMD gpu?

Hi @MCurto, would you please try to replicate/confirm this issue on your Intel Mac + AMD GPU combos?

I can , "unfortunately" took the day off and they are at work , only tomorrow.
I CAN'T replicate that with

Blender 4.1.1 Release Candidate 5fb26db5cc SHA 11 Apr 02:00 Intel
or
Blender 4.2.0 Alpha a656ce5c16 SHA 11 Apr 13:46 Intel

Both versions seem to be working just fine and 4.2 is now fixed for blacked out GPU output.Thanks.

on my home iMac+Somoma 14.4.1+580X tough.

As a side note: Trashcans have dual GPUs and some times I found it causes some weird glitches. Have you tried to enable just one GPU? Will test in other combos tomorrow.

Thanks all for the support in keeping Blender alive for older Macs.

I have, issue persists.

Will test in other combos tomorrow.

Please do, it seems to happen on older combos like my Mac Pro Trashcan

Thank you for taking the time @MCurto !!

@Caco-Oportot

So I tested Blender 4.1.1 Release Candidate b0f9c2f961 SHA 12 Apr 01:45 Intel on the Trashcan I have here (think its the most relevant to you) and if I use the 2 GPUs get almost instant out of GPU memory error, using just 1 is slow but works, it seems indeed glitched but only in Material Preview mode, seems ok to me in Rendered View mode (Screen Recording MOV attached).

Thank you for confirming the glitching issue @MCurto, it happens on the Material Preview indeed. If you add more objects with any amount of "transmission" to the scene, the viewport becomes unusable on Material Preview.

The "out of memory" error I assume is because the D300 on your Trashcan are only 2GB RAM, and mine has D500 with 3GB RAM so I only got that error on more complex scenes. I suppose the D700 (4GB) should run a little better on that, but not on par with newer GPUs.
