Here is one more video with more occurrences:
amaarora - it is very hard to deliberately recreate this issue, it seems to occur very randomly. But believe me, it is so frustrating when it decides to start happening, especially when I have to enter corrections into a large amount of text, it really slows down the work process.
Nonetheless I have managed to catch a couple of instances on video:
The first spasm happens at around 7 sec - on zoom change, and the other during text selection around 45 sec. I think it might actually have something to do with zooming in and out, since zooming in and out is also what makes the text reappear. That's how I tend to deal with this issue, but it's still terribly annoying. I've been wrestling with it for years, ever since I installed ID CS6 (which I still use). I'm on OSX El Capitain, but I also experienced this issue once when working on a Windows system in ID CC-something, so it doesn't seem to be system or version dependent.
I will email this to you as well.
