I'm getting some unwanted stretching along the corners. I was specifically trying to use style box textures on a button, but they seem to work the same as NinePatchRects, and upon testing I got the same result.
Lengthening the shape in the x axis seems to not cause corner stretching, but when altering the shape along the y axis beyond the default height corners start to stretch and distort instead of maintaining their aspect ratio.
I'm using Godot 3.5.1, and had the issue with 3.5.0 as well. Has anyone else had this problem and know any solutions? Or know if it's being fixed/changed?
