I found a horrible workaround for this… “Window 1” always seems to be the window with the incorrect zoom level (“pinched look”) with no obvious way to fix it. So, I created 3 total render windows under multi monitor and I am using “Window 2” and “Window 3” as my left and right monitors in “fullscreen” mode. “Window 1” I am leaving as a “windowed” mode render window that sits behind the fullscreen render windows so you can’t see it in-sim. This is probably destroying my frame rates having an extra render window, but it’s the only way to make my sim rig functional.
Let’s hope for a quick fix by the dev team or the community figures out a better way to fix/workaround the incorrect zoom level on “Window 1”.
