With regard to scrolling (full repaints) they make no difference, which you likely suspected. These are my scroll-up-benchmark times for one of my .org files: Emacs 27: 2.6s Emacs 28 No patches: 13.0s First 2: 13.2s All 3: 13.8s In terms of just repainting when I move the point, applying the first 2 patches made a noticeable difference. It is still sluggish compared to 27. I'm not sure I can tell a difference with the 3rd patch applied as well. It seems similar or maybe slightly faster. Aaron
