The larger font of 3.1 also has an issue in landscape mode. The data block for the selected target is shown in the upper right of the display. When the selected target is no longer received the residue of the left side of the target data remains displayed after the data block is removed. It appears that the "clear area" specification was not updated to correspond to the larger font size.

Result is an block of garbage at 2 o'clock on the outer range ring. It goes away when the target is deselected.
