Hi smurfendrek, Please check jarnos comment #89, you need to use light-locker, using dm-tool for lock is not recommended. You could also try with other screen lockers program. Also this is an old bug, if you are still experiencing the problem, please open a new bug. I am unsubscribing the security team from this ticket. If needed please subscribe it again.
