Graphics card:

Blender Version
Broken: 3.6.0, 14b112ef82, Main, 04-03-2023

Short description of error

Metal GPU Backend broken on Intel Mac AMD FirePro D500 macOS Monterey.

Cycles Viewport won't work as expected as detailed below.

Exact steps for others to reproduce the error

Open Blender.
Edit, Preferences, System, select GPU Backend: Metal, Save Preferences, Close Blender.
Relaunch Blender.
Default cube scene, select Cycles render engine, change Viewport Shading to Rendered.
You get intense flickering (strobo-like effect) of the whole viewport when you move or orbit viewport around the cube. Like it's redrawing everything on the viewport, and not only the shaded geometry.

Please look at the .mov (https://projects.blender.org/attachments/6a7ccbc1-aec6-4094-910f-650a9a95771f).

The actual strobo effect is much more intense than it looks, because the screen capture is only 25FPS.

~~It seems unrelated to discreet NVIDIA GeForce GT 750M 2 GB, as I temporarily disabled it and the same behaviour occurs with integrated Intel Iris Pro 1536 MB~~

It definitily has to do with OpenGL & Metal GPU backend. broken on both my Mac Intel machines.

Both these screen captures are from macOS Monterey.

The strobo-flickering one is from Cycles rendered viewport on Metal GPU Backend. The chameleon default cube is from Solid viewport on OpenGL GPU Backend.

Update/recap:

Both OpenGL and Metal GPU Backend broken on Intel Mac (Big Sur and Monterey)

OpenGL GPU Backend broken since: 3.6.0 3681ed377b main 04-07-2023
(last working version: 3.6.0 d34abea26a main 04-06-2023)

Metal GPU Backend broken since: 3.6.0 14b112ef82 main 04-03-2023
(last working version: 3.6.0 dc63f75837 main 04-02-2023)

Metal also broken on 3.6.0 74d24f9643 PR106535 so I'm guessing it might be related to #106672

Hi, thanks for the report. Please don't include multiple issues in single report.

On GPU Backend: Metal
Shading to Rendered, you get intense flickering (strobo like effect) of the whole viewport when you move or orbit viewport around the cube. Like it's redrawing everything on the viewport, and not only the shaded geometry.

I'd suggest to open a separate report for this.

On GPU Backend: OpenGL
changes to other colors depending on angle of view when you orbit viewport around the cube.
if you change Viewport Shading to either Material Preview or Rendered, the cube disappears.

If I'm not mistaken, these above issues are addressed by #106786 , right?

I don't know. I never seen/heard about the orange color. Is that only using NVIDIA GPU? or also present on the AMD GPU?

@Caco-Oportot Are you able to perform a bisect? (eg build blender from source yourself) This way we can bisect to the actual commit that introduced these issues for you.

Yes this report should only be concerning about the Metal change as that isn't related to the other task. Perhaps also add one for the orange color until we are able to reproduce it.

Same multicolor cube behaviour on both NVIDIA GPU and integrated INTEL Iris Pro (MacBook Pro w/Big Sur), and same on AMD GPU (Mac Pro w/Monterey) since 3.6.0 3681ed377b

I happens with OpenGL GPU Backend, when using the default Viewport Shading: Solid
(which I think is always Workbench?)

Please take a look at the .mov (https://projects.blender.org/attachments/bea04aa6-f670-408b-b905-1a8bd148e512)

I think it's related to the OpenGL/Eevee issue because it stopped working on the same build 3681ed377b, and both worked fine up to d34abea26a

@Jeroen-Bakker sorry I cannot build blender by myself, it's beyond my skills. But I can test any build you point me to.
