This seems to happen frequently with CSS filters applied to images - the initial image size is small, and when the image is fully decoded the surface size increases to the true image size. If a surface starts out at 12x12, the blur distance will be computed as 1/12 and that will still be used when the surface increases to the right size. Can be seen by manual inspection ofLayoutTests/css3/filters/effect-blur-hw.html PR 323730

"blur size" is the term used in the actual shader
