I have no clue. Try reconfiguring your build so it says "yes (system)" for 
almost everything, and especially anything related to fonts (fontconfig and 
freetype)

Qt Gui:
  Accessibility .......................... yes
  FreeType ............................... yes
    Using system FreeType ................ yes
  HarfBuzz ............................... yes
    Using system HarfBuzz ................ yes
  Fontconfig ............................. yes

Second, what is the font DPI configured to in both cases? Please provide the 
xrandr output and the qtdiag section related to screens.

I am talking only about X11. I have no clue about LinuxFB.
