The issue is after a slide moves in and out of viewport it seems like the full set of slides is jumping to the left and ruining the animation and display.
Any other way I could create this or get around the issue?
This is not a bug. A bug is when default functionality fails. You have applied transforms and transitions on the slider which conflicts with the way it is intended to function.
What you are trying to accomplish is not possible in Webflow without custom JavaScript.
