Hello,
Per the developer, this issue is not due to the time within the aircraft, but instead the latitude. The terrain radar image is available for 6 degrees lat/lon in each direction from the current position of the aircraft. As you are flying at 72 degrees latitude in the example image, the tiles are quite compressed in the east-west direction, so 6 degrees gives roughly 140NM. This is a design limitation, as increasing the number of tiles shown would significantly affect the FPS of the terrain display.
