Information from browser developer tools:

html tag computed size is flicking between 1920x883 and 1908x886 width and height attributes on <canvas data-testid="comeraimage-canvas"> seem to be flicking between 528x297 and 532x299 for all cameras (same models so expected that the values would match).
