It does if you zoom in beforehand.

The CenterDisplay functionality was lost when we did the HID thing; a
patch to add it to the two GUIs, most likely as an action
CenterDisplay(), and re-add support for restoring zoom and position,
would be greatly appreciated.

Alternately, create a new layer and add a mark (via, line, circle,
whatever) to this new "DRC results" layer.  Then, a hotkey that's
"find a mark on the DRC results layer" would add the vim jumping to
that.
