Hi!
In the latest version (19.0.0.59) after rendering a stock chart it blinks 1-2 times. (The data points and background disappear and appear again). Similar thing happens after selecting a period.

If you cannot reproduce the issue I happily send a video too.
Platform: macOS Google Chrome, but the same happens is Safari.
Thanks.
