Yes, I too have seen this issue with InDesign CC 2017.0 only intermittently.

For you is the issue document specific, or does it happen with all documents?
The issue happens on random document and occurs occasionally and doesn’t necessarily persist in a specific document. It doesn’t happen in the document in the video anymore at this moment, as a matter of fact. I made this recording a while ago.
I’ll try your suggestion when it happens again and see if this solves the problem.
