Actual results: Massive whiteouts. Looks really ugly. Expected results: No or atleast less whiteouts

Summary: Scrolling whiteouts with two fingers → Scrolling whiteouts/checkerboarding when panning through lazily populated element (Sencha)
Still seeing this in 53.0. Also whiteouts for similar techniques, for example https://clusterize.js.org/. Any progress?
Still present in 56. Do you need any more info?
The solution for this involves fixing the dependency bug (which exposes the displayport to web content) and then updating sencha and other similar frameworks to use it for their virtual scrolling implementation. So this will take a while to fix, but admittedly I should try to push harder for the new web api to be standardised.
Tried today in latest dev edition (58b7), not any better. Is there some kind of workaround one could use? (as a component author)
