How to fix Konsole font?

After updating to RHEL7 from RHEL6 my Konsole fonts are looking ugly and un-antialiased(Monospace size 11 in both systems). I played around with font antialiasing system settings but I am unable to make it identical to how it was before. Is there a way to restore the looks of font? i.e by copying some old font file or some settings from old system? Same issue is there for my Gvim.
