When I switch from my custom workspace ('Dave') to Preview and then back to Dave, the preview window shows a vertically-stretched version of the selected image. This only lasts a couple of seconds then reverts to a normal size image. Even more pronounced switching between Dave and Filmstrip (that's stretched horizontally, and also briefly mucks up the screen layout). Screenshots below.
This doesn't seem to affect operation at all and like I say only lasts a couple of seconds, but is visually very distracting and certainly doesn't happen in Bridge 2022.
