Once again remind people that FBTFT works for both busses: SPI and parallel,
the latter one is usually GPIO-based and quite slow (I have one of the panel in
this mode, it gives me ~2-3fps at best on a 10y.o. x86_64 embedded device).

Maybe that's the reason? In any case, I think the datasheet on the panel should
answer the question.
