Now on 2.0.2.9, but for a few releases now things have been much slower for me.

When that older fix for recurring tasks was out at 2.0.2.5, things were snappy. I could see a large recurring nested task set instantly update when marked complete. I think the 2.0.2.6 or 2.0.2.7 repaint cascade updates are what made things much worse.

Now, I mark any task completed and the entire task list disappears for multiple seconds before refreshing correctly.
