I have ubuntu 18.04 default xorg (1.20.4). I tried to add this:

>Section "ServerFlags"
>    Option "Debug" "dmabuf_capable"
>EndSection

to my "/usr/share/X11/xorg.conf.d/20-intel.conf" but still - couldn't reproduce
an issue.

Mesa libs were exchanged in ".profile" file, all windows are using iris
(checked with /proc/$PID/maps)
