The top and bottom of the tiled image bleed through the bottom and top of the imagelabel, especially when its TileSize is something like {.15, 0}, {1, 0} where the label is expected to show a single clean horizontal row of the tiled image. Vertical tiling is broken in the same way (not pictured).
It’s noticable when the image is only slightly stretched.
Of course stretching the image further makes it even more visible.
It’s very close to behaving correctly though, only a pixel or two off (on both sides).
Probably irrelevant, but it looks the same on all GraphicsModes I can try (Vulkan, DX11, DX9, OpenGL).
Reproducing shouldn’t be hard, but here’s the file in the screenies:
