My PHPStorm is unconfigured. Few days ago, editor has space between number line and gutter icons like this image:
How to remove this space? Thanks!
That looks like Distraction Free mode active .. or unwanted post effect after exiting Presentation mode (happens sometimes).
In first case -- just exit "Distraction Free mode" (from View
