(This suggestion was posted on the steam forums, and messaged to the support team. I was told to also place a suggestion here as well. I hope reposting the suggestion here, as well, won't be a problem.)
So, a lot of people (with AMD GPUs) can't see others in VRchat thanks to this cubed pardox shaders/amd issue. As a temporary fix, would it be possible to add a checkbox in system that forces all shaders using the cubed paradox shader, on the persons (clientside of course), to be the standard unity shader, and possibly with the smoothness setting on zero?
This inclusion would serve as a temporary fix (or permanent) for the issue for AMD users face, such as myself.
AMD recently fixed this issue, update your drivers and you should be able to see people using Cubed Shaders again.
And how would they know you're using his shaders? Shaders aren't some special identifiable thing, they can be edited and customized extensively with little effort.
