My atom got annoying line on tab bar


Hi, I installed atom on my mac. here is the screenshot

how can I get rid of the line. is it bug?


That’s annoying indeed.
Just some questions: have you tried resizing the window or moving it around? Does it happen with Atom only? Have you tried using the inspector the check whether that line exists somewhere in the window HTML? Have you tried to run Atom in safe mode?


oh I found it already. I checked Show tab bar. That is the cause. Thanks for your reply!
