Bug Strange pink lines glitch after light baking that happens only in the editor

This happens after baking the light and does not happen when entering play mode.
I tried changing the mesh, the bake settings, I searched the forums but no one has seemed to encounter this issue. I updated my graphics driver too and changed to the newest LTS version of Unity.

 

Try the CPU Lightmapper to rule out any GPU Lightmapper issues (because it's preview as in "not production ready").

Do you get any warnings in the console, such as "could not fit into lightmap" or something like that?

It would help to know what settings you changed. Surely it wasn't all of them? I would start with disabling the three checkboxes and turn off lightmap compression. If that doesn't help, lower the sample counts. Just to see if any of these affect the issue in some way.

 

I don't get any warnings. I only changed the realtime lighting settings. I changed to CPU Lightmapper and disabled the lightmap compression but it seems to still happen right at the start of the baking process

 

So I changed the view mode to UV overlap and I got this

Perhaps the UVs are causing this?

 

So I tried some different view modes and I found something while selecting the Albedo one. The baked light is offset? I have no idea what is going on.

 

So I finally fixed this issue by moving the entire map by one meter upwards. This avoids the strange Z fighting.
