It's a bug, a very annoying one at that.
It helps if you have saved your view as a placed camera.
Render your view, abort the render, double click the saved camera in the project map, re-apply 2 point perspective. This should force everything back to normal for one render. If you do another render, it is the same process again.
This also happens with sketch render engine.
It's made doing renders in AC21 quite a chore.
Edit: also make sure you have Render Safe Frame on.
