I think the gist of an install-anywhere utility is to build-in all
dependencies. They could make it use the system libs etc if recognized
but that just gets more complicated. So, I'd expect them to look

They are both anti-aliasing, but yes, they do look distinctly different.
Hopefully someone can help figure this out but I'm a bit skeptical
(despite my lack of concrete knowledge in this are) that you are going
to get a native look in lots of environments when you are specifically
trying to avoid dependence on the particular environment by using
AppImage. Can't wait to be proved wrong. :] Good luck.
