My screen fonts are:

I guess these are standard fonts?

Yes, pretty standard.

I tried download the latin modern fonts and using them instead of Times New Roman. It did not make any difference, unfortunately.

No, it should not. I doubt they are really usable as screen fonts, actually (but I may be wrong).

Here is a video of the problem:

Thank you for the document, I will try it out when I find the time (my main machine is linux).

No sluggishness here (Linux Mint, LyX 2.3.2). No noticeable hit in terms of CPU use either.

I have a copy of LyX 2.3.1 running under Win 10 in a VirtualBox environment. That's a bit sluggish all the way around, but I noticed no difference in the (slight) lag between the first and second pastings of '123'.
