Issue
Significant overlap and lumpy connection points can be seen in گُلْشَن:

Compare with Gulzar:

Strange lumpy connection points can be seen in many other words. To name a few:
سَلْتَة

مِحَبَّت

This seems to be an issue with how the glyphs are shaped to combine together. It will affect many words. Some to a lesser degree, some to a greater degree. Unfortunately, that probably means a good amount of redraw.
