Alignment flaw

I drew three half-circles, filled each one with different colors, no outline, and aligned all to the bottom.

But I noticed there's a flaw in the alignment, because one of the colors appears below the objects when editing the file and when I export it to an image.

Is it a bug? Is there a fix for it? TIA.

  • When exporting as a bitmap with anti-aliasing enabled, what I see for that bottom edge can depend on how that edge is aligned (or not) with the pixel grid. If that bottom edge is "pixel perfect" with respect to the pixel grid, then I get a perfectly clean, sharp edge in the exported bitmap, with just the pure colors.
