This is freaking annoying me. I don't know which option do this, but it is really bothering me so much.
The problem is that WebStorm add a "virtual" space after each text like function or object (picture 1). You can see it because clearly in the highlight text (picture 2).
Also, when I am writing on a line, the text is push right to the caret (picture 3)
I want to know which option is it, to disable it.
There is an open issue for this problem:
It definitely helps to select a different font, but reinstalling the latest version of Source Code Pro font may also help.
It should be already fixed in latest 2017.1 builds.
