I'm using Ubuntu 14.04 and font hinting works perfectly as usual, except for a couple of applications: Dropbox's preferences and Dwarf Therapist. Since they are both Qt apps, I figure that's where the issue is.
Here's a picture of Dropbox's preferences:
If you zoom in you'll see that the font hinting is in greyscale:
I created a
~/.config/fontconfig/fonts.conf file with this in it:
<match target="font"> <edit name="rgba" mode="assign"> <const>rgb</const> </edit> </match>
That seems to get some color subpixel hinting, but then the letters look even thinner and wispier (here set in comparison with Diodon's preferences, which displays the system font properly):
Is there a way to get these fonts to display correctly? Ideally the application would obey Ubuntu's defaults (hinting, the font itself, etc.).
I did install
qt4-qtconfig, as explained here, but that did nothing. I'm not sure if this is a bug (under what package would I file one?), or something weird with my install. I feel they should just work without without editing a font.conf file (since every other program in Ubuntu ignores those), though if someone can give me the right settings for the font.conf file I'll be happy.
