Aryx, on which OS is this?
Sorry, Windows 8.1 64 bit, 1.25 device pixel ratio.
I see the border all the time in my 8.1 VM scaled with 100% and also 125% and 130%. Also tried with layout.css.devPixelsPerPx set to 1.25.

Do you have somewhere a style which removes the rule at ?
When launched in safe mode, I see the line until I select the window (is not selected, maybe because of the dialog to confirm the safe mode). Then the space between the tab and the top edge of the window widens and the line disappears.

Code looks fine to me, if the visuals are also good then this should be ok :) r=philipp
