Splitting a clip could leave both halves showing the original (now-wrong) audio waveform for several seconds. Trimming was worse — the thumbnail and waveform didn't refresh at all until you noticed something looked off. Both now clear and regenerate immediately.

Audio waveform decoding is also now cached per source file, so repeat edits and reloading a project update instantly instead of re-decoding the whole file every time — and dragging a trim handle updates the waveform live as you drag, not just after you let go.

Also fixed a bug where shrinking a clip down small could leave its trim handle stuck, snapping the clip back to full length just from hovering near the edge.

Fixed stale thumbnails and audio waveforms after splitting or trimming a clip.
