Were you able to reproduce the problem? I didn't have time to try, sorry. Too much stuff on my plate, and still only 24 hours a day, even with Emacs 30... > Yes, I see no reason for having the highlight overlay on something that can't be seen. > > But how do we know what the viewport will be in `rectangle--highlight-for-redisplay`? Since it is redisplay that determines window-start and window-end, and it hasn't run yet, this puts us in some kind of chicken-egg situation. Maybe it has to be done inside redisplay. It has to be done with the display code, but does not have to be as part of redisplay. We can use functions like vertical-motion, window-text-pixel-size, posn-at-point, and other similar APIs, which all employ display code that performs layout-related calculations without actually displaying anything.
