this was exactly my observation as well... remove fonts-liberation2.  it's increasingly
difficult with containerization/snaps, etc.

Ok, I solved the problem. There were many coincidences playing a role in the
original report.

For starters the (real) regression in fonts-ubuntu triggered my attention, but
unlucky testing against Liberation Sans revealed a change in hinting between
fonts-liberation and fonts-liberation2, which wasn't installed on my reference
system. fonts-liberation2 lacks proper hinting (which showed on my 23.04
system) but fonts-liberation is properly hinted (on the 22.04 machine). Once
installed, fonts-liberation2 overrides all Liberation fonts, except for
Liberation Sans Narrow.

Removing fonts-liberation2 and downgrading fonts-ubuntu to fonts-
ubuntu_0.83-6ubuntu1_all.deb seems to solve all the reported problems.

My apologies for the noise and thanks for adding your thoughts to this!
