Cant adjust map window size.

[Kn1ghty]

Hi
due to my graphics card being faulty and needing a replacement i have had to go back to playing from 4K to 1080

now i cant change the size of the map window i can adjust the size of the map but not the window itself

im not talking about the circle map

i cant move to the bottom to get the part on the corner to adjust it coz if i move the window as far to the top as i can i am still only halfway down the window

i know it can sound confusing

anyone know what i can do?

when i press x on my 360 joypad that opens the window but theres a big wide open space apart from the top left hand corner of the map in the bottom left corner of the tv, i cant fly and adjust the map at the same time
