@Jeff, I don't believe calling UpdateAllItems() would have big impact on eeschema's performance given the graphical complexity of even complex schematics. In v6 we'll have view item updates in eeschema handled automagically (as in pcbnew), so I wouldn't spend too much time on this bug for now.
PS. I don't see the clipping issue anymore on today's nightly.
