Status: RESOLVED DUPLICATE of bug 1392713

(Firefox :: Theme, defect)

Description

[shawgum]

Attachment: line above loading dot.png

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:57.0) Gecko/20100101 Firefox/57.0
Build ID: 20170822100529

Steps to reproduce:

Open any website and when it is loading, look at the loading dot icon which move to the left and right.


Actual results:

There is an extremely thin line above the dot when the dot is moving to the left, while it is good when the dot moves to the right side. My machine is XPS with 4K screen so this could be why the line is extremely thin but it is there.


Expected results:

No line.
