1. Didn't take a screenshot of that one. It's in New Haven, to the bottom left where there's that little garden. The passability is a bit confusing there. You can't step on the grass, which probably is intended, but you CAN step on the (I think) white flowers. And the actual glitch is, you can walk on the walls.
2. Elvenia - first screen. You can walk down that cliff.
Spoiler: show
3. Elvenia - screen with the rogue raflesias. You can walk up the tiny waterfall.

5. Elvenia - after finding Susanna, going east to the next screen (2 waterfalls here)

6. Dilldel - You can walk behind the pond at one spot.
