animation flickering

Hello!

Description

When we run two animations at the same time we can observe some flickering on elements. I see flickering happens with an element that gets visible. It looks like the element become fully visible for a moment and after this the animation starts.

Noticed the problem in these browsers:

• Safari Version 11.0.3 (13604.5.6) for MacOS
• Chrome for iOS

The most interesting is we have the issue with jQuery starting from version 3.2.0. There is no issue in versions before 3.2.0.
