The OBS main window UI is so broken/corrupted as to be unusable. The menu bar is missing, preview doesn't work, and some elements are sort-of moved to the top where they shouldn't be. Resizing the window makes things much worse -- screenshot attached.
Bizarrely, it seems to be fine in the live environment and in the snap package. That doesn't help me much as I need v4l2sink.

After further experimentation, I discovered that this issue only occurs under certain multimonitor configurations; specifically, in the case of two side-by-side monitors, if the right display's top edge is higher than the left display's top edge. If the right monitor's top edge is aligned with or blow the left monitor's top edge, the window renders correctly.
