Today I decided to upgrade from older version 3.7.0 of GSAP. And I found out that about 1/3 of my animations stopped playing when they should.
I narrowed it down to versions 3.8.0 and 3.9.1 between where the issues happens and does not.
To reproduce:
1. Open the Codepen in /debug page (so as if it is just normal page without all the Codepen fluff)
2. (Kinda optional?) Position page scroll so that "scroller-start" marker is after "start" marker. Or in other words, scrol
Sorry about that, @ncla! I see exactly what you mean and it should be fixed in the next release which you can preview (compressed) at https://assets.codepen.io/16327/gsap-latest-beta.min.js
It was related to the "lazy" functionality that defers and groups rendering of .from() values to maximize performance.
You can fix it in the current version by simply setting lazy: false on your .from() tween(s).
Thanks for reporting this!
