New 19.4 MSDK env: Running sample_decode will cause "segmentation fault (core dumped)" by adding "-r" option in X mode.

[bbao3]

Hi, I installed the latest 19.4 MSDK and media-driver with all the required dependencies. But there is a new "segmentation fault (core dumped)" issue in this new release package. Reuse sample_decode of 19.3.1 can replicate the same issue, so suspect this issue is related with rendering. But since it belongs to MSDK package, can you help to find the root cause?

The command and log output like below:
root@intel-dbg:/opt/intel/mediasdk/share/mfx/samples# ./sample_decode h264 -i /video.h264 -hw -vaapi -rgb4 -r
libva info: VA-API version 1.6.0

Hi @bbao3,

Seems it`s regression in LibVA (since intel/libva#351 merged). On latest libva master all works, but on tag/2.6.0 (which provided in release) sample crashes.

Thank you AntonGrishin, so will we release another MSDK (e.g. 19.4.1) later to make sure end-user will not be confused with this LibVA issue?
