Sometimes artifacts can be seen on the edge of filtered elements. The artifacts can be reproduced more often if a perspective transform is also applied to the filtered element. Additionally, pinch-zooming can cause the artifact to disappear/reappear.
I think this is because we are not insetting the UV sample bounds by 0.5 pixels in all directions in the brush_blend
shader. The inset ensures that bordering pixels are not included when sampling from the render task region.
