For 1080i H.264 and VAAPI - bob deinterlacing, i have halfscreen (top) compressed image.

Other solution is to take nighty builds as complete mesa package via :

Please correct the problem to the official Ubuntu repos.
This is supposed to be fixed in Mesa 20.1 git by c81aa15d, gallium/ auxiliary/ vl: fix bob compute shaders for deint yuv. /gitlab. freedesktop. org/mesa/ mesa/-/ commit/ c81aa15d646215e ac38c8e0b6dc1a1 0b35bc13c3

This could be backported to Mesa 20 if someone wants to try it.
