So spaced repetition is of course designed for memorizing facts, not learning and integrating complicated concepts, but the danger of memorizing a particular visual presentation of the question prompt is well taken. My only suggestion would be to prepare multiple versions of the same question. This might initially lead to the different versions being collectively shown more often than the ideal spaced repetition frequency for a single fact, but assuming learning is transferring between version (i.e., they are reinforcing each other), maybe it works out in the long term? Very interested to hear what others suggest.
