[Mesa-dev] frontends/va/postproc: Use the actual image height when blitting

[Ilia Mirkin]

Hi Thong,

In this change:

https://cgit.freedesktop.org/mesa/mesa/commit/?id=49465babdb35d88ed8a283e925d6cd346255d50c

You appear to change the height of the underlying resource while doing
a blit. This is never legal though -- the height of the resource is
effectively immutable (and subject to various constraints). I'm not
sure what issue you're having, but this is not the way to fix it.

Cheers,
