Actual results: A black line across the top of the browser. It is not there when I use my laptop normally, only when I connect the 4k screen. I tried installing the beta browser, but same result there. Expected results: The black line should not be there.
What app is the third icon from the left in your system menu bar? Does the problem go away if you disable it?
That is LastPass. I tried disabling all Add-ons, but the line is still there (at least I'm pretty sure I did). I'll doble check tomorrow to verify.
I was referring to the OS X system menu bar, not the Firefox toolbar. There is an icon in the system menu bar with a mouse cursor over a title bar.
That is Cinch. I doubt it has anything to do with it, but will check.
Have you had a chance to check?
Hi, it was a bug in FireFox. The line dissapeared after the lastest update, so all good now.
Interesting, thanks. I was probably involved in fixing that then, I just don't know what could have fixed it. Anyway, glad it works now!
