#1 - First check list of supported devices, for AMD HEVC is supported from the Carizzo APUs and up. But my Kaveri is out of luck. My GPU RX570 is however in.
#2 - There's Microsoft HEVC codec available for a small fee, believe it or not, to some actually helped. Visit microsoft store and look up HEVC.
#3 - Reinstall your GPU driver. This should come as a first.

As of my previous post, it actually helped but added strange behaviours for some videos, where there were mini loops, instead of proper playing forward. The core of the problem is indeed combination of APU and GPU, where first one doesn't support it and the second it does. For whatever reason, the first messed up the things.
