Why does this white static bar keep showing up over my tabs?
Every once in a while my 15' MacBook Pro has this white static bar that appears over my tabs (as seen in the picture below). Occasionally it looks different but this is the most common. It never happens when I am on a particular site either it just randomly occurs. I am just curious what this means and how I fix it. I am not very computer savy so try to keep it simple haha thanks!
