First time playing around with Looking glass.
Having issues getting it to work properly, need help tweaking my config and/or finding out what is causing this error.
Running VFIO setup through libvirt on Fedora 34 with SElinux running in permissive mode.
VFIO is verified working and everything with 80~ FPS in cyberpunk @ 1440p.
What am i doing wrong?

Looking glass config:
set up through guides on ArchWiki and the official Looking Glass guide from looking-glass.io
tmp file exists and is modified on boot: /etc/tmpfiles.d/10-looking-glass.conf
[root@fedora tmpfiles.d]# cat 10-looking-glass.conf
#Type Path Mode UID GID Age Argument
touch /dev/shm/looking-glass
chown delta /dev/shm/looking-glass
f /dev/shm/looking-glass 0660 delta kvm -
also the looking glass “driver” from the SHMEM device from redhat for windows is installed.
I have tried both the bleeding edge version and the cutting edge version (both on client and host, respectively)
Running the looking glass .exe manually on window (after stopping the service) gives the following messages:
