Standard Shader Unity 5.5

Hi guys, im pass now for unity 5.5 and my standard shader look like this, with lots of artifacts and pinks… Can anyone help?

Is this on a new project started in 5.5 or converted? I’ve been seeing a bit of this but not experiencing it myself. I can’t seem to replicate it.

I start a brand new project…

It kind of looks like a 16 bit texture that is interpreted as a 8 bit texture. It seems the only source can be the skybox/reflection. Can you change the reflection source in the lighting window?

A few other people have posted similar issues. I believe one person reported completely uninstalling and reinstalling Unity 5.5 fixed it for them.
