I'm also using vbridger

that could be a question for vbridger server as something on how vbridger is tracking you moves when you blink

i just tested and its def make more obvious on vrbridger but ti pops up subtly when doing normal web cam https://gyazo.com/53b550c4b30a9392b645772363ab277b

maybe smoothing would help?

maybe... or sensibility.... calibrating... you can ask on vts server
