Ahem, not really.  XRGB is the only one which works in practice, and
virtio-gpu kms driver will stop advertising anything else soon (patches
should land upstream with the next merge window).

Do you have a reproducer for that?

There is sdl2_2d_check_format() which reports the supported formats.
If we hit sdl2_2d_switch() with a format not whitelisted by
sdl2_2d_check_format() we have a bug somewhere in qemu ...
