--- Comment #19 from Jan-Marek Glogowski <glogow at fbihome.de> ---
The drawing is completely done by Qt (using QPaint::drawGlyphRun), just the
layout is done in LO. I checked Qt5Graphics::DrawTextLayout, and it has the
correct font (dumping pFont->family()).

Then I opened a KDE font selector with a preview, like in kwrite. If you switch
between GFS Artimista and GFS Didot, the preview doesn't change at all. Since
the width of the glyphs is different for quite a few characters, as you can see
in Michaels attached example, there should be a difference. And also the "t" is
very different in both fonts: its bar aligns with height of "e" in "test" in
Artimista but not Didot, and seems too small in Didot generally, so should be
easy to spot.

I suspect the displayed charmap program doesn't use Qt, as we know Cairo based
font handling isn't affected. And since Cairo also works here, it's very likely
a Qt upstream bug.
