Issues with Highlight Canvas: Zooming Bug and Performance Concerns

is highlight canvas experiencing a bug? When i try to zoom in on a bunch of highlights it then jumps to a completely different part of the canvas. I always find the highlight canvas too slow so might need to give up on it for analysis, but don't recall the jumping around so much. Video attached for reference, you can see it jumps to a different part of the canvas at the end of the recording.
