the video explains much better than i can. when i updated to 4.3.9, i started getting random errors when increasing the height above what it was. other upscaling methods work, but i need nearest neighbor for obvious reasons.
edit: i don't use windows 7, it's just a theme using classic shell. I use the normal install version of paint.net on windows 10
edit 2: if anyone knows how to downgrade, lmk so i can still use paint.net while waiting for a solution
