When this has been reported previously, it was caused by “fingerprinting resistance” tactics employed by the browser (i.e., queries to the browser about the size of the browser window returns dimensions that are much smaller than the actual dimensions, to thwart browser fingerprinting).

The work-around is to dig into your browser settings and disable the fingerprinting resistance.
