Bug in block edges invisible

Hi there,

I switched from Rhino 5 to 6 this week. It is great, goog job!
Now I came across the following problem:
All my outer line of the 3D Solids are gone the moment I created a block and edited it.

It looks like this:

When I open the block it looks like this:

I use a variation of the shaded mode.
Can anyone please help?
Thanks in advance

Hello- can you please run the SystemInfo command in Rhino and post the results here?

Hello - does the default shaded mode look correct?


No, unfortunately it does not.

Could you post the file so that we can try to reproduce this?

I drew the object again and created a new block and the bug was gone. Unfortunately I overwrote the file and can’t reproduce it.
Should the bug come forward again, I will post the file immediately for you.
Till then: Thank you.
