Thanks for all your help. Using Magick had no effect so I've had another look
at my setup. It turned out I had this in m
\setupexternalfigures
[maxwidth=\textwidth,
maxheight=0.8\textheight.
location={local,global},
]
The period to end maxheight is obviously a mistake. (However, I'm still
perplexed that this only shows up when the image is rotated...)
Sorry for the noise.
