What causes all the patchy squiggles and marks over so many runways and taxiways?

Why do they look like this and can it be fixed?

i should think that is on purpose, to make it more realistic
there are a number of 3rd party addons that change the airport ground textures but they dont work on the hand crafted big ones.

More realistic?

Yeah totally… I always see blobby patches of weird patterns on runways

WHAT!??? NO.
