Fun fact: the Forma (and I'm guessing other Mk. 7 devices, and potentially the Kindle Oasis 2 & PaperWhite 4, too) doesn't actually support anything other than PASSTHROUGH & ORDERED .

c.f., pxp_dithering_process @ drivers/dma/pxp/pxp_dma_v3.c

Requesting something else indeed triggers the "Unsupported dithering mode" warning .

Also, requesting dithering on a specific region (as opposed to the full-screen) may noticeably shift things around on the horizontal axis in that region (possibly because of PxP alignment constraints).
