ArcGIS API for JavaScript 4.18 transparency issue when scrolling

ChrisCable — Mon, 15 Mar 2021 22:48:41 GMT

When scrolling a map layer in 4.18 that has a transparency value set, the view draws over any cached areas resulting in the layer briefly appearing as if no transparency is set, then fading to the correct transparent appearance. The resulting "pulsing" of the layer is unacceptable. This behavior is new to 4.18.

I have created a demo here: https://mapping.northernbeaches.nsw.gov.au/test.html

Scroll around and you will see what I mean. Any advice is appreciated.
