Hi UEMdev,
Did you use the Win10 v1809 SAC release without OSOT? So just next-next-finish? I am running v1809 LTSC with OSOT. Will try without OSOT as well, just to be sure.
BTW, I also have VM running (v1809 LTSC with OSOT) in VMware workstation (no Horizon) and experience the same issues there. Also the traces are the same compared with the ones from VDI.
