Steps to reproduce:

1. Maximize the Fx window.

Actual results:

Bottom border should not change thickness.

> 2. Display the menu bar.

Does this happen when you use the toolbar context menu to display it permanently, or when you hit alt to show it temporarily, or both? Does the issue go away if you unfocus the window and/or restart?

Happens with the menu permanently showing and if using the Alt key.  Problem persists after a restart.  Problem will disappear if I unmaximize the window. Unfocusing the window retains the thick border.

FYI..  I can fix this problem by adding some css code:

#main-menubar > menu {
  min-height: 21px !important;
  height: 21px !important;}

I don't know if this helps but adding this css code improves the look of the separator:

#nav-bar[currentset*="unified-back-forward-button,urlbar-container"] #forward-button > .toolbarbutton-icon,
#nav-bar-customization-target #forward-button > .toolbarbutton-icon {
  padding-left: 8px !important;}

Please disregard comment 4, it was destined for a different bug report.

I just ran Nightly Fx30 under a VM and I don't see this problem.  I'm guessing it might be a video card issue.  My VM uses a virtual generic video card.  I use an AMD HD7970.  I also tried with HWA off but that didn't work.

Just nailed it down.  It's a HiDPI issue.  I run at 120 DPI.  I set layout.css.devPixelsPerPx = 1.0 which gives me 96dpi in Fx and the borders are fine.
