I was thinking maybe hardware issue so I picked up a vega64 to try in place of the rx580. same issue. I think I finally have a reproduction pattern though. It seems that doing a screenshare in microsoft teams will trigger it. I am starting to wonder if it is more an iGPU issue and that encoding video triggers it?
YES, and if you turn it off and set your SM to iMac Pro 1,1 their is a good chance it will go away. Others have said the issue with the 580 on iMac Pro 1,1 and needing dummy kext has been resolved with the latest release of Mojave but I am not sure about that; I left it even after the update. In addition normally the removal the IGPU and use of iMac Pro 1,1 will also make iTunes DRM function correctly.
