Gizmo is offset from vertex I'm using Blender 2.8, doing retopo for a sculpted model with Shrinkwrap modifier and sometimes enabling Snap. Some of my vertices have their pivot oddly offset and it's making the shrinkwrap modifier perform badly.

As you can see in the screenshot here, I have selected a vertice but the actual pivot to move it around is off to the side and below it. This is not the case for all of my vertices, and does not change if I switch between different pivot point "styles" (individual origins/median point/etc.)

How do I fix this and "reset" the transformation center to be right on the vertex itself?
This happens, because Gizmo doesn't take modifiers into account.

According to this developer thread and this developer thread it's a current limitation, and no way around that.
