Hey Brian thanks for your feedback.
I tried all different formats, tried isolating computers via team render, and it seems that the bug is somewhere in the Transparency channel.
I started checking on and off channels in the texture, and the blocks only appear when Transparency is enabled. Also, there are multiple pieces of geometry in the top piece that is flickering, I’m trying to merge them together today to see if that helps.
