Intel VAAPI howto with Leia v18 nightly based on Ubuntu 18.04 server
Upstream vaapi is working mostly with gstreamer. So if you could reproduce with gstreamer and vpp then chances are much higher, that the intel people would like to fix it. So could you try the samples with gstreamer and vpp methods (0,1,2,3) and see if that works?
First decide what functions / features you expect from a system. Then decide for the hardware. Don't waste your money on crap.
