“Corrupted looking photos on Safari

Hey all, Safari has been loading corrupted looking image files that are somewhat pixelated”

Reset your SMC and your NVRAM:

Sometimes changes are made to the system and then settings (i.e. for Screen Resolution) become corrupted, in the meanwhile. So, reset both on your Mac. See where it goes from there. It’s worth a go.
