--- Comment #4 from Marek Kašík mkasik@redhat.com --- Hi, thank you for the screenshots.
freetype has changed default hinting engine in 2.7 from v35 to v40. The change is more apparent when the antialiasing is off. You can reproduce it in e.g. ftview by running "ftview -m "This is a test text" 19 /usr/share/fonts/dejavu/DejaVuSansMono.ttf", turning off antialiasing by pressing "a" and then you can switch between the hinting modes by pressing "H". Upstream won't change it back and so we won't too.
If you prefer the older hinting engine, you can select it by setting environment variable "FREETYPE_PROPERTIES" to "truetype:interpreter-version=35" in e.g. ~/.bash_profile. Or you can have a look whether a newer set of fonts would suit you better with the default hinting engine.
I'm closing this as notabug since the change is intentional (and looking at the freetype mailing list, they know about the visual change of DejaVu fonts).
