It&#x27;s probably to do with the snark - intentional or otherwise - in your leading &quot;Whoops!&quot; - it comes across as &quot;hey, everyone, I&#x27;m really clever because I found a flaw&quot; which a) several other people found anyway b) you didn&#x27;t actually report accurately; as others point out, the &#x27;wobbling&#x27; is the positioning algorithm still running, nothing to do with scrolling c) is an edge-case; no matter what your claim that &quot;200 points aren&#x27;t a lot&quot;, most timelines I&#x27;ve ever seen online have had nowhere near 200 points. It&#x27;s also painfully obvious before you even begin that 200 labels won&#x27;t fit at all sensibly in the given width, so nobody using this library would actually make such a blundering mistake.
