If you file in the attached tweaks, OB scrolls just as smoothly as the standard browser. I'm not sure if the tweaks have side effects though; you might want to verify that (in particular because of the comment in OBColumn>>switchFilter: which indicates some interference although I can't see how that could make a difference if the filter is identical).

That is awesome, thanks! It seems to work fine; I've removed the comment. It's probably out of date, and if there are visual oddities, the fix is undoubtedly somewhere else.
