Bug Description
Ubuntu release:
Ubuntu Bionic Beaver (development branch); the problem also occurs in Kubuntu 17.10, if upgraded to Plasma 5.12.x
Package version (plasma-workspace):
Installed: 4:5.12.4-0ubuntu2
Candidate: 4:5.12.4-0ubuntu2
Version table:
*** 4:5.12.4-0ubuntu2 500

100 /var/lib/
What I expect to happen:
To continue where I left off after waking up my screen, without having to kill and re-run plasmashell
What happens instead:
When the screen (external monitor, not a laptop) turns off due to a timeout, whether this was set in Plasma's power management settings or using xset dpms <whatever>, and I wake it back up again to continue working/faffing around online, any widgets have vanished and the desktop is a solid, unresponsive black.
The rightmost edge of my panel is still visible in the top left corner of the screen.
"Hot corners" and compositing still work; windows are still decorated.
Apport is silent.
This does not happen if I wake the screen back up within the first couple seconds, but after ten seconds or so it happens reliably every time.
It also does not happen when I don't set PLASMA_
Using Xorg. Proprietary Nvidia driver, tested with 384 and all 390 point releases.
