Please put Kodi debug mode, reboot so we capture a clean log, then play Jellyfish 10-bit HEVC test media (not pirated files), then pastebin the entire log (not snippets) with "pastekodi" and share the URL generated so we can understand the host more.
Also share the full debug log from the Arch box too, assuming it's also using a current/recent version of Kodi. Info on the graphics stack there (versions etc.) would be interesting.
