This is a regression from 22.10 to 23.04 and Ubuntu(-mono) has seen some
changes since 22.10, so let's compare the same font, because I do suspect
weird (libfreetype?) behaviour on Ubuntu 23.04 which I can't explain.
Attached is a screenshot of OpenSans-VariableFont_wdth,wght.ttf using the same
commandline. It clearly shows bad hinting and I'm convinced this looked better
hinted on 22.04, so I suspect it will look correct on your system too?

I also attach the hinted non-AA ftinspect view of the same font.
ftview and ftinspect were compiled against freetype 2.13.0. As far as I can
tell, I'm using libfreetype 2.13.0 to render fonts on my system (I don't know
whether that's important for ftview and ftinspect?)
