Well, the linear gradient on this rectangle doesn’t look right… one of those WTF moments. Quite amazing how something like this can happen… no rotation applied, no other layers involved, just a very buggy (seemingly exponentially buggy these days) design software
Hey, sorry to hear this is happening! I’ve tried to recreate this from my end but was unable to. This definitely seem strange though, would you mind reaching out to the support team directly via this form for help: https://help.figma.com/hc/en-us/requests/new
