Once a time open my favorite editor and saw strange artifacts around. My tabs become squared small and ugly (1).
And the worst is that My text now surrounded gray background that flickers and disorientating me (2).
I will be very graceful if someone could say how to make my editor great again because even total reinstalling of Atom can't fix my problem and it installs already broken. Thank you very much!
P.S: Operating system - macOS Sierra 10.12
