In gst-libs/gst/vaapi/gstvaapiwindow_wayland.c:302, around the "XXX: use VPP to
support unusual source and destination rectangles" comment, you could #if 0 /
#endif the if() block to unlock you temporarily. Though, this is not something
I would push, a proper solution is needed, as indicated. :)

(and this is what is to be available for the next release BTW).

An alternative is to try something in vaapisink too, but this is more involved
to validate because there are multiple combinations to consider and that also
impact the X11 backend. One solution would be to use the cropped size to
guess-estimate the window size. Though, this is also just a workaround because
there are situations where vaapisink does not control the allocation (creation)
of the window. So, we end up to need a generic solution in
GstVaapiWindowWayland::render().
