Line distortion when vector tracing — joins between strokes distort instead of connecting smoothly
When using Image Trace or Auto Trace in Illustrator, the traced vector lines often distort at junctions where two strokes should meet cleanly. Instead of forming a natural join, the curves warp or bulge slightly, creating uneven intersections that break the flow of the line.
It looks like Illustrator is over-smoothing or misinterpreting the corner geometry at those points. A more accurate “preserve joins” or “maintain line continuity” option would help produce cleaner, more natural outlines — especially for minimal line art or hand-drawn illustrations.

This is a variant of T-junction problem, a well-known one in the field.
Despite several papers were published on the topic (like this one from 2015 — https://cecilialeiqi.github.io/vectorization.pdf) it was never properly addressed by Ai team. Seconded this.
I hope this request would help to grab more attention!
