Here’s a question. Do the shadows disappear if someone uses the ghost power-up? I ask because on iPad, which only supports the basic smudge shadows, they do not. Which does make it quite easy to spot where someone is when they use the ghost power-up.
BTW, if the double shadows is the road that Zwift wants to go down then it really needs to fade out the basic smudge shadow in full light. Only bring in the basic smudge when there is low light. It looks awful with two shadows. One of the rare times I appreciate being on the lower graphics settings.
