An intermittent bug that pushes the map up out the top of its window leaving white space

an intermittent bug that pushes the map up out the top of its window leaving half a screen or more or white space below. It mostly occurs after creating a new activity, or closing an existing one.

It can be quite persistent sometimes, other times i don’t see it for ages. Happens in Brave and Firefox, but one pushes it far higher than the other. Maybe thats a clue
