The editors are being worked on, but it does not break wikis. Bouncing is not something I experienced, but some elements take longer to load which pushes down the content area in stages.

WikiActivity was not replaced by Recent Changes; Recent Changes has always existed. However, the new version does have changed spacing and longer lines because of all the tags, so it can be daunting to people who aren't used to it. It's definitely more cramped than the old version. You can set up filters to break up the lines a bit.
