This is our referenced versions:
Kernel: 5.2.0 (however 5.1.5 should also work) 
Xorg: 1.20.4 reporting xrandr version 1.6
Libxcb: 1.13
Xcb-proto: 1.13
Xorgproto: 2018.4-4
Libdrm: 2.4.95

Also, you can reference the status of drm leases support:

When you tried this work https://github.com/intel/Igvtg-qemu/commit/2881d9a65beb319c42b947d23eb1d260224bcddc, did you add "enable-drmlease=on" mentioned in the commit message?

Tina
