Hi All,   I've dumped about 8 hours into this so far and have made almost no progress.  I'm hoping to find suggestions for motherboard bios settings, linux config settings, VM xml tweaks, or anything else that might help resolve this.GPU is the Gigabyte RX 560 4GB Rev2 with AMD Bios Version 17.8.1 (have also tried v18+ with identical results). It is functional, but has intermittent issues with the HDMI Audio Driver and either fails to start games, or shows artifacts within the game.Sys
