It's a total edge case, but just to quickly note here:
When using the fade effect, it's not necessary to use the "wraparound" option - it's actually causes an odd little jump/toggle.
So, when you see this odd toggle you can either:
- Turn off wraparound (recommended)
- Add a 3rd image
- Switch to slide effect
The first one's, of course, the logical solution. 😉
