Isn't it a duplicate of https://github.com/intel/compute-runtime/issues/488?

I installed new version of Plex (plexmediaserver_1.29.2.6364-6d72b0cf6_amd64.deb) to confirm if hw accelerated tone mapping has been fixed there. Indeed it works correctly now with hardware acceleration (at least for experiments...
