Hi @elextr I really appreciate the attention being dedicated to this issue! I'm trying out Geany 1.39 and I would say that the scrolling is an improvement from 1.38, but Geany 1.39 overall feels sluggish.
I specifically notice: - About a ~150ms delay between performing a scroll and the scroll occurring - Running simultaneous instances of 1.38 and 1.39 makes it very apparent that switching between different code tabs is much more sluggish in 1.39 (the sluggishness is still there with a 1.39 instance running alone)
I'm not sure if other users are having this experience. I wonder if this could be due to other changes present in 1.39?
