With that try build I'm still able to reproduce it at 130% zoom on my 2560x1440 screen, but on no other zoom levels. So it would just be a noticeable improvement.

Since this is triaged and has a priority set, marking this fix-optional to remove it from regression triage. 
Happy to still take a patch in nightly.

Confirmed bug 1501195 fixed this as well.
