AI Runner v1.15.2 is a patch that includes two enhancements

Drawing tool

You should see a bump in performance here. In the previous version the drawing tool had a bug which would expand the base image each time lines were drawn to the left or top of the 0,0 mark - this has been patched and the image will only expand to the line boundaries.

Eraser tool

In previous versions the eraser didn’t look great - when erasing quickly it would essentially just erase ellipses with gaps between the them. Now proper lines are erased as expected for more accuracy and control over what you erase.
