I tested the patch. Unfortunately the chosen implementation to paint the subpath separately does not work out. There are 2 problems I can see:

1. When a shape has a filling and you create a shape with a hole in it like a doughnut it now also fills the hole in the center as both path are handled separately which they should not.
2. If you have a gradient background each subpath shows the full gradient inside itself instead over the complete shape.

I have uploaded a test file which shows both problems and screenshots with and without the patch
