Base layer bleeding through
I've got a base layer with 2 buttons, which send the user to one of two layers. There are triggers set up so they have to view both layers before the next button appears on the base layer and if they choose to revisit a layer, I've set them to resume saved state so they don't have to sit through the animation.
The problem is- of the 20 people who have tested the published training, 4 or 5 can see some of the base layer bleeding through the top layers.
I've attached the .story file and a screenshot of the problem. Anyone have any ideas?
