Comment 64 for bug 1684240

Hello,
this is really annoying problem and apparently nobody cares except for the people that experience it.
But I have found a better workaround that works at least for me:
In /etc/init/sddm.conf after line:
    exec sddm
add:
    killall sddm
    exec sddm

Just restarting sddm automatically right after it strated. No more logout/login manually.
