Hey,

https://invent.kde.org/graphics/krita/-/blob/master/plugins/impex/tiff/tests/data/quad-jpeg.tif is the file in question.

What we'd need is to get the bitmap as interleaved, uncompressed YCbCr, since that's what our rendering engine ingests. Based on how the other compression formats behave like, it seems that what gets out of libtiff right now is the raw JPEG-encoded strip.
