Strange white rectangle boxes

Hi All,

I'm getting a white rectangle box on the screen when I'm in Resolve on my MacBook Pro/Users/famelittle/Desktop/Screen Shot 2020-08-12 at 6.57.00 PM.png

Can u list a pix?

I wonder if this has been solved yet.
I just upgraded to 17.2.2 and I'm still getting this quite regularly. Only restart fixes it for me.
Here's a picture of the latest one:

Man, that's a tiny image. Can't see anything useful.
