I have also encountered this issue on Windows 10 Edition, on a custom server, with a custom Resource Pack and Behavior Pack.
Steps to Reproduce:
Join a custom server (i.e pe.mineteria.com).
Walk around for a while, or switch servers if it's a network.
After some time, skins, models, players, blocks and GUI's will start turning pink.
Observed Results:
Entities, Blocks and GUI will start to turn pink after playing on the server for some time.
Expected Results:
Entities, Blocks and GUI should not turn pink at all.
If requested I can provide more images of the issue.
