Resolution Note:
This isn't a polyspatial issue, but is an issue with how they have constructed their scene which has a lot of Z fighting between transparent objects. The person who built this scene I do not believe understands how z sorting and transparency works.
Transparent objects are sorted by the distance of their origin. So if you have many wide, tall, transparent objects, like quads for a UI panel, their origins can often be at the wrong distance as you rotate around them.
This user either needs to use the canvas system which will deal with this issue itself. Or they need to switch as many shaders as possible to be opaque to get around transparency sorting issues.
