** Description changed:
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
- 500 http://de.archive.ubuntu.com/ubuntu bionic/universe amd64 Packages
- 100 /var/lib/dpkg/status

What I expect to happen:
To continue where I left off after waking up my screen
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 , 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_USE_QT_SCALING=1 (but I
use a Hi-DPI screen and would rather have Plasma scaled correctly).
+
+ Using Xorg. Proprietary Nvidia driver, tested with 384 and all 390 point
+ releases.
** Tags added: scaling
