Lines in reflection probes

Hi I'm having a strange issue where lines are showing up in my reflection probes no matter what I do. Please see attached image. I'm using Unity 2017.2.0f3. It happens even when I create a brand new one.

Thanks

 

So I found out that this is happening when I bake all the reflection probes at once. If I do them individually this doesn't happen. I'm thinking this is a bug and will have to do some more testing to see. If anyone has a better answer please post

 

I'm still having this problem on a different project now and a whole new version of unity.
