Material Transparency Issues (not sure why previous post got autoflagged)

Hi There!

Been a user of Sketchup since it came out ages ago. This last version or two Ive noticed this Style transparency issue where if on Nicer I get this odd Moire Effect but on Faster it goes away. I Cant seem to solve it. It happens whither its a straight color with opacity or a texture with transparency

Does anyone know how to solve this? its been annoying for some time to me. I can only upload one picture it says so here is a screenshot of an xray where it happens on all surfaces once transparent. Just the pink top is transparent. If I turn transparency to Faster it goes away.
