Bug Description
After enabling Virtual Desktops when I wake up from sleep and switch desktops I get a black screen.
Steps:
1. Log in with Plasma on X11
2. In System Settings select Workspace Behaviour > Virtual Desktops
3. Create a layout of 2x2 (two rows with two desktops each)
4. Put the system to sleep
5. Wake the system up and enter your credentials
6. Switch to a different desktop to the one you are wither with a key combination or clicking on it on the taskbar.
Outcome:
A black screen will be shown instead of the desktop. If you try to go back to the original desktop you will still have a black screen.
Expectation:
For the system to switch virtual desktops without any issues.
Workaround:
1. Change virtual terminals using Control-Alt-F4, for example.
2. Change back to the GUI virtual terminal with Control-Alt-F1
3. The graphical interface is restored and you can switch between virtual desktops without problems.
Alternatively I imagine that removing virtual desktops would work, but that reduces functionality.
Things I tried:
1. I purged all the nvidia drivers and installed the last version 535. It worked briefly but it quickly reverted to the same issue.
2. I have tried login using Plasma on Wayland and I can't reproduce the problem. Unfortunately I have some applications that aren't supported yet that require using X11.

I cannot reproduce this with intel graphics. Adding nvidia.
