Blender Version
Broken: version: 2.83 (sub 9), branch: master, commit date: 2020-03-15 22:43, hash: rBf06a6e92bc5e
Worked: (newest version of Blender that worked as expected)
Short description of error
I compared the 2.82 and 2.83, found 2.83 edges more thinner in edit mode, even only half a pixel, I don‘t know whether this is a functional improvements, or other causes of the problem. This is not friendly in modeling, even not easy to see in some dark materials; whether we can go back to the previous thickness, or to provide the options in the theme setting.
Exact steps for others to reproduce the error
