Description

STR:
* In Fennec, open https://medium.com/comedy-corner/10-tricks-to-appear-smart-during-meetings-27b489a39d1a
* Once it loads, try scrolling down by just scrolling once.

What happens:
There are various rendering artifacts near the the url bar area. This doesn't happen on Chrome.
The reporter is talking about the underlying background layered underneath the document that is shown while scrolling. I'm able to reproduce this on Nightly when scrolling down, as I scroll down I see small portions of the background become visible (the light blue in my attached screenshot I bordered with red).

See screenshot.

This is only reproducible with the dynamic toolbar enabled and doesn't look to be a new issue.

A minimal test-case showcasing the problem on a simplified page would be helpful to isolate the issue and to detail what kind of markup yields this issue on particular pages.
