Bug: Timeline Scrubbing studder between clips

When scrubbing on timeline between clips, there is always a studder/pause/hickup between clips where the playhead freezes for half a second. Even when using ProRes codec and "snap" disabled, it still happens. When scrubbing within a clip, it scrubs smoothly but as soon as I go past the clip into another clip, the scrubbing playhead freezes/studders for half a second or for about one second.
