There seems to be an offset issue with the auto paint line filters:
As you can see with the Horizontal lines they end before reaching the end of the page, As for the Vertical line they end before reaching the bottom of the page.
The page is just a 300x300 image to show the effect.
I am able to replicate the issue. I will get this queued to fix. Thanks for reporting the issue!
This is fixed and will be available in 23.04 when it's release.
Fixed - The Auto Paint Horizontal Lines and Vertical Lines filters were not drawing to the edge of the page.
