Why is this line here


I have recently updated my Atom and some Plugins. Since then, I´ve got a white line running trough my code. But its not that middle line (the blue marked one) it is completely fine, but the red one is getting on my nerves because I can sometimes not read my code anymore.

Does anybody know how to remove that line ?


Does the line appear when you start Atom from the command line with atom --safe?
