On second thought, my quest doesn't actually have any scrolling screens (I was going to have one but removed it). Come to think about it, I may have reworked my quest to not have any side-scrolling maps because I encountered the same issue you did (it's been a while and I am forgetting).

I tested my quest out with a side-scrolling map and have similar issues to what you describe.

You'll probably get better traction with this problem if you open an issue on the gitlab repository: https://gitlab.com/solarus-games/solarus/issues

This problem is completely avoided by using the fade in/ fade out effect instead of the scrolling. Though it doesn't give the same exact effect as scrolling, it is much better than 'immediate' transitions (but not as good as Star Wars transitions).

The problem has to be reported in order to be fixed.
