1. Open attached project
2. Open "Probuilder_UnlitShaderIssue" scene
3. Walk around in front of red surface with cube behind it.
4. The imagery behind the transluscent red cover keeps glitching out, becoming fully opaque at times, loading parts or none of the objects behind it

Expected: It should not flip out based on what angle you are looking at it from
Actual: Behaviour changes if you walk around and look at it from different angles
