Looks like this is an issue with picture cache invalidation, you can see this when enabling gfx.webrender.debug.picture-caching. Only tiles which the starry image touches get invalidated, which leave some tiles with leftover blur.

Hi Emilio, I wasnt able to repro this now. Does this still repro for you?
