No.

Yes, sway hangs and I can't switch vt, but ssh session works normally
and I can recover control over vt after killing sway via ssh.

dev.drm.__drm_debug is 0 by default otherwise /var/log/ would eat all free
space.

Thanks. I'll report back with the logs tomorrow, it is late where I am to do
that now.
