Short description of error
This bug was in 2.79 and was fixed, but it seems that is in 2.8 Beta too .
Unwrap Error StarTestBlender28.blend show how bad it is.

Exact steps for others to reproduce the error
To reproduce this, just select all faces in the image then do an Unwrap ( any setting it's the same ). It's the same bug like in 2.79 that was fixed in there, but in 2.8 Beta wasn't fixed .

Confirmed. Not sure what happened, the code appears to be the same.

Actually I think the unwrapped result is ok, but the ngons are drawn with poor tessellation in the UV editor.

The thing is that. I'm trying to bake a texture from one model to the other. And in Blender 2.79 works flawlessly after you implemented the uv ngon code .
But when I try to do that in 2.8 the bake it's broken by the tessellation errors .
Here is 2.8

Here is in Blender 2.79

I reproduced this bug in blender 2.79b, but not the latest daily build, so it appears the bug has been fixed already.

Please try the latest daily build: https://builder.blender.org/download/
