Well, as for the regression it was actually "kind of" performance related in so far as it didn't update because it ended up "processing" (though almost all of it was actually sleeping, not using CPU) longer than the time between two keypresses. A possible issue might still be for files with very few keyframes where seeking would happen with too much distance between displayed frames so you can't get a good impression of what is happening.
