I guess this is one for @matherp.

When using the ARC command on an ARMmite F4 (Ver 5.05.08) I am getting an extra pixel displayed. It appears to be at the top left corner of the imaginary square enclosing the circle that the arc is a part of. I have tried a couple of F4 modules and different LCD panels, but the results are always the same. See below image for an example. These arcs were drawn using the following 3 commands:

ARC 200,100,75,76,0,180
ARC 100,100,75,76,270,360
ARC 100,120,75,76,90,180

As I'm not sure how well the single pixel points will show up in the image I have circled where they are and drawn a link to which arc each is associated with.

Could you please take a look at this?
