I've been having a noticeable lag in the UI since the debug stuff was added. I have a really powerful computer, so I doubt it's that. The UI was always super snappy for me, autocomplete was really fast, windows appeared very rapidly.
But the last couple versions, I've notice a lot more lag when windows are opening or the autocomplete/typeahead is doing it's thing.
Did I miss a setting or something? Or is something just really wrong with me.
