Minor graphical inconsistency

Not a problem, but just a minor graphical inconsistency that I noticed.
I operate JT65 with a 4KHz receive filter from the carrier frequency up to 4K. The upper limit does not lie on the 4K line, but just to the left of it. It should line up with the decimal point and the grid line. Please see attached screenshots. Or is the display correct and I have misunderstood something?
I would like to take the opportunity to wish you all a Happy Thanksgiving.

It isn't a problem per se, but a consequence of how the display grid and filter are "drawn" in relation to the total width of the panadapter in pixels. There are several math functions used to calculate and draw the position of the grid lines based on the display zoom level which is related to the FFT bin width size. At some combinations, there are going to be times where a drawn element does not fall on even pixel distances from center and since a pixel is an atomic display element, the result is a drawn display object may be off by a pixel. Since the filter is symmetric around the carrier line, I suspect the grid line is probably rounded up to a larger value by a pixel1
