Missing XDG_RUNTIME_DIR++ causes zwift to not launch.

[netbrain]

Was installing zwift on a new machine today, backed by the nouveau driver. And it failed to create the window:

$ DEBUG=1 zwift
$ docker run -d --rm --privileged --network bridge --name zwift-netbrain --security-opt label=disable --hostname netbox -e DISPLAY= -e ZWIFT_UID=1000 -e ZWIFT_GID=1000 -e PULSE_SERVER=/run/user/1000/pulse/native -v zwift-netbrain:/home/user/.wine/drive_c/users/user/Documents/Zwift -v /run/user/1000/pulse:/run/user/1000/pulse --env-file /home/netbrain/.config/zwift/config --device=/dev/dri:/dev/dri -e DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/1000/bus -v /run/user/1000/bus:/run/user/1000/bus docker.io/netbrain/zwift:latest

01dc:err:winediag:nodrv_CreateWindow Application tried to create a window, but no driver could be loaded.
01dc:err:winediag:nodrv_CreateWindow L"The explorer process failed to start."

However when adding the environment variable XDG_RUNTIME_DIR, WAYLAND_DISPLAY and mounting the wayland socket it seems to work again.

docker run -it --rm --privileged --network bridge --name zwift-netbrain --security-opt label=disable --hostname netbox -e DISPLAY= -e WAYLAND_DISPLAY=wayland-1 -v /run/user/1000/wayland-1:/run/user/1000/wayland-1 -e ZWIFT_UID=1000 -e ZWIFT_GID=1000 -e PULSE_SERVER=/run/user/1000/pulse/native -v zwift-netbrain:/home/user/.wine/drive_c/users/user/Documents/Zwift -v /run/user/1000/pulse:/run/user/1000/pulse --env-file /home/netbrain/.config/zwift/config --device=/dev/dri:/dev/dri -e DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/1000/bus -v /run/user/1000/bus:/run/user/1000/bus -e XDG_RUNTIME_DIR=/var/run/user/1000 netbrain/zwift:latest

Can anyone else confirm the same behavior? @sHedC ?

Works fine on my other machine, and both have Xwayland installed, so not sure why it's behaving differently.

Not really sure what's going on with this, but i've seen some complaints on missing XDG_RUNTIME_DIR on some occasions, but propriatary nvidia driver seems to work with and without this. So maybe only a nouveau issue?

Closing it, as i didn't dig any deeper.
