I can confirm your guess. By making the texlive fonts available through
fontconfig I can reproduce all your results. Independently of whether
the debian package fonts-lyx is installed or not.

This definitely is a Qt issue, because the debug patch is still able to find
the right fonts. I don't think there is anything we can do. So, either choices
about where to put lyx fonts will work, provided that the texlive fonts
are left out from fontconfig management.
