Final tile in 2x2 grid with uniform tile sized checked is not uniform.

I set up my workflows to use a 2x2 uniform tile layout with each tile slightly larger than 1/4 the size of the final image to improve output quality (i.e. so the model has a better chance of seeing enough of a face to not turn the output into a Lovecraftian horror). When it gets to the 4th tile, rather than being uniform in size, it picks a small section in the bottom right corner and renders that instead. Usually this doesn't cause a problem, because seam fix goes back and fixes it, but occasionally decides something down in that corner is a face or the like because the area is too small for the model to get enough context, and messes up the whole workflow.

Does anyone know, is this a bug, or is there a way around this issue?

I have the same problem.

Hello. I was wondering if anyone found a fix for this. I still get this problem where USDU starts rendering a small portion from the edge of the image when the final tile is finished.
