I'm not sure if that is a bug at all. You can set: Settings > Notifications > Lock Screen Notifications = OFF

When a monitor goes to sleep, it switches off the HDMI audio channel connected to pulseaudio, which causes a notification, which causes the screen to switch on again. Then the lock screen goes to sleep again after a timeout. Rinse, repeat. Fixed by switching off lock screen notifications for pulseaudio, but this was a head scratcher for a good few months. Suggested fix - don't cause notifications to wake up a monitor.
