jetbrains ide – Some text is not showing in PyCharm

A few days ago I noticed something changed (for the worse) in my PyCharm.

Some of the text that I have in files is no longer visible. The only way to view it is to double clock the space where the text is and then its highlighted. Otherwise I can not see the text.

This affects all file types in my PyCharm including .yml and .py.

This is the code inside the file:

    something:
      new 1: {try: fail}
      old three: {again: no}
      interesting and: {box: none}

and this is what I see:

Does anyone know what is causing this issue? I looked around and was unable to find a way to fix this.
