Leave animation randomly makes leaving element flicker on IE11 #2338
in transition code:
The flicker I'm randomly experiencing is the element returning to normal state when leave class is removed, just before the element is removed from DOM.
Moving the removeClass(this.el....) to next tick seems to resolve the flickering.
We've managed to capture the flicker on video happening on IE Mobile (IE11 Update for Windows Phone 8.1):
Here's a simplified repro: http://codepen.io/sztrzask/pen/MKxZvO
It really does seem like IE bug.
Delaying the cleanup phase seems to work around it (with appropriate guards in case elements were removed).
