Named view thumbnails go black

As someone who uses named views a lot, I am wondering why occasionally the thumbnails go BLACK and then… at some point correct themselves? Not a biggy - but just curious.

I have an NVIDIA P2000 and it is updated.

It’s hard to say. Thumbnails are created when you save a file.
If something interrupted that process, or otherwise compromised the image, I suppose a black thumbnail could happen.
I’ve never had it myself, but I rarely pay much attention to thumbnails.

Is there some pattern you have noticed that seems to result in a black thumbnail the next time you go look?

Interesting @John_Brock. I thought that maybe it was a common occurance but seems it doesn’t seem to be, I’ll keep an eye on it and see if there’s a pattern.

Thank you.
