Blurred shape overlay gives lines

Add white shape above image, Screen, with extreme gaussian blur (r=1000). Gives discoloured lines as below. It's not rendering (export to jpg shows it too). Experimenting shows lines appear when blur radius gets to about 500px. .afphoto file is 484mb. I can upload to somewhere if you like.

Hello @dmstraker,

the same here.
I filled a shape with gray color and apply the gaussian blur,
after export as JPG file, are the grid lines clear to see.

see the screenshot
