On some multiplayer servers, I've been pested by a small "minimap" that shows a miniature of the theater of operations, like the one shown in the picture.
The only way I can get rid of this is to disabling the HUD completely, but then I cannot see the 2D gauges. This map is only present on some servers, not all of them.
What is this, and do we have a way to hide it? Tried all key combos that I know, and even tried to move it out of the screen, but to no avail.
If this is an option that only the server can adjust, I would like to know what is the purpose.
