Bug#998637: kwin-wayland: Black screen and cursor only after resume from suspending with kwin-wayland

["M." <infinity.probability@gmail.com>]

Package: kwin-wayland
Version: 4:5.23.2-1
Severity: important

Dear Maintainer,

After resuming from suspend, only a black screen and a cursor is shown. Only shifting to a TTY
and restarting SDDM or rebooting gets a login window. This only happens with Wayland on KDE. X11 is fine.

Changing to LightDM or starting by hand does not change this behavior, as removing the option
to not lock the screen after resuming from suspend. I lost already a lot of work because of this.
