Hi Daniel,
I think what would need to be adressed is that when it "can´t" interpolate, ease the restrictions that bring the interpolationi to this point. I mean.
From an older answer of your, similarly "On the corners, we are missing data to interpolate. The best we can do is inside the convex hull of the raster.
"
So what I would suggest is that increase the radius where it is search for a pixel with value until it is found.
Rasterize tool, corner line bug

He, he, that's theoretically possible, but someone has to do it ;)
