Yep, lets try that way.
It is very hard to design thin icons that are recognizable on a chaotic map.
Having a reliable level of contrast below the icons would help. In the menu they are displayed on high contrast. Using the same icons on a map is much easier with a background imo.
The compass could definitely profit from a circle so it is more in line with the center-view dot design.

The scale in its current form however makes much sense to display without background because it helps to grasp the dimension/scale better when the map is visible beneath it imo.
