Hi csheany and thanks for reporting this issue.
As per the attached video I was able to reproduce the issue on the latest Nightly build (68.0a1-8th of May) using a Google Pixel 3XL (Android 9) phone.

Notes: I wasn't able to reproduce it on Firefox 66.0.4 nor on Firefox Beta 67.0b18.

Thanks,
Andi

That is rather curious.

Regressed by bug 1525181.

P5 as the minimap is not a user-facing feature, but this would be nice to fix to preserve the utility of the minimap for development purposes.

This issue no longer occurs with the WebRender implementation of the minimap added in bug 1604280.
