With an updated tree you shouldn't see _any_ full-screen update for typing characters generally, except occasionally when you cause a rebreak that changes paragraph height. Otherwise only the current paragraph should refresh. About the flickering, I don't know. You could verify with my earlier published PAINTING debug patch, precisely which rows are getting updated by the LyX painter. Did the patch apply cleanly? That means you must have the singlepar stuff in your local tree... strange. - Martin
