--- Comment #3 from fluffy <flu...@beesbuzz.biz> ---
This happens on the 5.1.5 macOS build as well.

The nature of this bug makes me wonder if the export is compositing the layers
after scaling, rather than compositing the whole image first before scaling it
to the target size. Is that the case, and if so, is there some reason for it to
work that way? That could cause issues with accuracy with alpha blending on
more complex images.

The obvious workaround from an end-user perspective is to currently save out
the image at its current resolution and then to use an external tool such as
Imagemagick to resize the final image, or doing a select all/copy merged/paste
into new image that then gets scaled down. It would be nice if the export
function did that automatically, though.
