When 'show coordinates' are turned on, they are displayed in the top left-hand corner of the iPad screen. However, since the iPad Pro 2018 has a strange resolution, the coordinates are not fully visible and are hard to see. With the GUI scale set to the largest, 0, they are somewhat visible and still unnecessarily difficult to see. Moreover, with the GUI scale set to -2, the smallest, it is nearly impossible to see the coordinates, especially if in the hundreds. 

Included pictures display this at all three of the GUI scale. Coordinates are shown at the top left-hand side.

I assume this to be an easy fix, and hopefully will be fixed as playing with a small GUI far more enjoyable on a smaller iPad screen.
