When using the Line Width or Line Detection nodes in a screen pass. Depth Width lines are not generated correctly.
For comparison:
When Depth Width is used in a mesh shader.
When Depth Width is used in a screen shader.
Honestly kind of embarrassed that I didn't notice this sooner. Since I've been generating lines in the screen shader directly for ages now. I'd guess the issue is being caused by normal depth not being properly passed into Line Detection when in the screen shader.
