E.g., how do you deduce > from "seven hundred something" that there were more than 10 redisplays > per second? Well, I set the counter to zero and then measured ~60 seconds. In that time, there were 783 redisplays IIRC. That gives an average of 13.05 redisplays per second. >> Of course, it's still possible that during the 10 seconds where the >> cursor was invisible on the screen there hasn't been a redisplay of >> the selected window, but how can I know? > > If your Emacs is configured with --enable-checking='yes,glyphs', then > you can invoke "M-x trace-redisplay RET", and see every entry to > redisplay_internal announced on stderr. Ok, I'll try that out. I'll also try out the 0.53 interval to check if that cures the issue for me, too. Bye, Tassilo
