System Information
Windows 10 64 Bits.
Graphics card GeForce GTX 1080 Ti.

Blender Version
Broken: version: 2.83.1 hash: 1af8e0cc6c

Short description of error
Wireframes becoming extremelly jagged at certain degrees (43,45,90...) especially in Object mode, previously they crisp and clear.
{F8311376 size = full}
Exact steps for others to reproduce the error

Default Scene.
Switch to one of the ortho View.
Switch to Wireframe mode.
Edit Mode disable Face display option.
Rotate the Cube (43 or 45 or 90..) degrees.
Switch between Object and Edit mode.
Wireframes are jagged.

Based on the default startup or an attached .blend file (as simple as possible).
Two files using the default scene from each, not that it matters but just in case it's needed.

A few more additional information:

The bug presents in Object Mode and on the outer selected object outline.
The bug can be reproduced with the default blender settings + cube switched to wire-frame shading. No rotation required to see it.
It is broken in,
blender-2.82-windows64
blender-2.83-ddda1af97afc-windows64 (from Jan 2020)
blender-2.82-linux64.tar.xz
It worked in,
blender-2.81a-windows64
blender-2.82-367def2f1605-windows64 (from Oct 2019)
blender-2.81a-linux-glibc217-x86_64.tar.bz2

*tested on Windows 8.1 64bit (with graphic driver) and Ubuntu 18.04 64bit (default LiveUSB settings with no additional driver)

Update: Bug also tested to be broken in,
blender-2.82a-windows64

Unable to test on blender-2.83-a103d09df485-windows64 due to blender crashes on start.

git bisect give 6d3eb85f66 as the faulty commit

But the commit message say :Note that the aliasing is a bit worse than the old FXAA that we used to have.
So it might be intentional.

Yes unfortunately it is a regression. But that is because of performance improvement of the new method.
I did not managed to get it to the point I wanted but achieving better result is doable.

I just don't have the time to dedicate to this issue for now.

If anyone is willing to help, the file is outline_detect_frag.glsl and the function is diag_dir.
