<p>Thank you for your quick response.</p>
<p>I checked the draw call of the cells, but it is never executed on scrolling. I attached the exported requests/response(Chrome/Save as HAR with content, I hope it's enough) for both 3.3.4 and 3.3.5.</p>
<p>I added another screenshot of a simpler case that does no custom painting but is also slower. It is a button that changes it's CSS on click.</p>
<p>Possibly it is worse if drawing actually occurs, because in another example I checked updating two cells is more than 10 times slower.</p>

<ul></ul><p>Hi Koen,</p>
<p>with 3.3.4 the performance seems to be ok again.<br><br>
We will switch back to 3.3.4 and try to isolate a testcase, that shows the problem.</p>
<p>best regards<br><br>
Max</p>
