Current behavior:
While I scroll an ion-content with some elements inside (div, ion-grid, canvas, custom objs), randomely one or more items disappear… With safari’s debugger i can see the html structure and css right, but they remain invisible on the display…

Expected behavior:
The elements should not disappear.

Hy,
I’va got same problem with Ionic 4. It seems that it all come from Ionic component on Html.
I mean :
if I use “ion-button” it will sometimes disapear
if I use “button” all is ok

same with …etc,etc

My only solution was to remove all “ion” cmponents but strange that nobody answer other?

Regards
