Major Problem upgrading SP v11.0.3 to v/11.1.2

Has anyone encountered issues upgrading from v11.0.3 to v11.1.2 (any version above 11.0.3)?

Specifically, I am getting crazy black and white striations in my viewport when in 'material view' mode (see grabs) when opening in v/11.1.2

This only happens with some of my projects (about half of them). All of the projects I have tested were completed in v/11.0.3, and textures were successfully imported/applied to the same corresponding meshes in UE5.

A few notes:

- All of my projects (good and bad) have the same color management settings (see grab)

- All of my projects Channels (good and bad) are perfectly fine in isolation.

- The only thing that chills out the 'striations' is turning off 'Activate Temporal Anti-Aliasing' in the Display Settings. This only chills them out a little though, just enough to see materials peeking through the harsh white lines.

I have tested every variable I can think of and have reached a dead end in my brain.
