Not sure I understand. Did one of the tools crash when converting the source?
xnconvert isn't maintained by this project.
Or do you mean there were problems with the encode (artifacts, color shift,
etc.)?

the fact that "webp lossless.webp" has smearing green artifacts seems to
indicate
that the problem occurs *before* compression, since the compression is lossless
afterward.
I suspect the resizing filter to introduce smearing.
Also, the lines in the source are anti-aliased. See the zoomed region attached.
This complicates the down-scaling, since the antialiased colors are melted into
the final pixels.
If possible, best would be to directly generate this synthetic image at the
final size (1920x1080) instead.
