Can confirm, it's a bit choppy when scrolled with a touchpad really fast. I very much doubt this is a Plasma 6 regression though as the delegates were only just recently ported to be lighter weight than they were in Plasma 5.

Comment 2 Arjen Hiemstra 2023-10-31 08:36:25 UTC

Scrolling has always been a bit problematic, partly due to ProcessModel not being properly threaded. It's one of those things that I'd love to fix but which isn't severe enough to warrant the massive amount of work it takes.

The scrolling feels smooth on Plasma 6.5 beta.
