Resolved since posting - resolution below...
Fairly new to GSAP and loving it!!
I have a section that is simulating a horizontal scroll and using containerAnimation to do this.
When I load the page on empty cache, it works perfectly, positioning and everything is great. Then I reload the page and the positioning seems to be out if I viewed the animation on the previous section. I then have to clear cache again to view the animation with the correct positioning.
I have made a video here:
As you can see, on the first load, I scroll down to the 'our work' section and it looks good. I then refresh the page and it knocks the positioning out then the third time I clear the cache and once again the positioning is good.
I'm really at a loss with this so any input would be great, perhaps someone else has come across this or someone a little more used to GSAP can point me in the right direction?
I added the CodePen and seeing the same issue here - please view in full screen though as I havent yet worked out the responsiveness fully so works best at 1080
One thing I did try adding was ScrollTrigger.refresh() to see if this helped but didn't get anywhere with this unfortunately.
Thanks in advance for your input
