Last line overlaps bottom of screen with --fullscreen

[vid512]

When maximized, the last line can (depending on Y resolution / font size) overlap bottom of the screen, being cropped and not fully visible.

Example:

I would prefer Nvy to set up one less line, and fill the rest with black.

I have a similar problem, but on a different scale. At my workplace, two monitors are positioned on top of each other. When Nvy expands to full screen, the window occupies the total height of the two monitors.
This is not critical for me, because if you expand the window through the button in the header, everything is fine.
