Short description of error
The display of the Shading workspace is glitchy... the two globes in LookDev mode show as solid black and when rotating the viewport they have a solid white "shadow". Adding a material has no effect. Adding a new material has no effect when changing Base colour in the Principled shader for example. This is also true of all modes... Solid, LookDev and Rendered. Material shading has no effect. And the white "shadows" break up and disappear when rotating the view.
Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).
I have a feeling it just may be a limitation of my Mac hardware. But I just want to be sure since I have downloaded multiple builds and they all display this way.
