--- Comment #2 from Marek Kašík mkasik@redhat.com --- There is a new hinting engine in freetype since 2.4.12. It was turned by default in 2.5.0. I can not change it.

Fonts are specially broken in GTK apps.
This looks like a problem of the specific font. If you could find which font is shown on the screen it would help us and we could file a bug against the specific font.
