I found the culprit regarding unnecessary scalar redraws, or at least I
found a way to make it bearable when not editing:

I made a Windows build with the suppress-redraws patch applied:

I wonder if it makes things quicker on your end. Also, I'd be
interested if you notice any negative side effects.
