Sometimes, when I switch to a different activity, Plasma crashes.

STEPS TO REPRODUCE
1. Switch to a different activity

OBSERVED RESULT
Black screen occurs, then I have to reload it with `plasmashell --replace`

EXPECTED RESULT
Should be able to load normally

Backtrace of crash at startup

I attached the backtrace of my first reboot after I upgraded to Plasma 5.17

Backtrace after I tweaked Plasma Renderer settings

So after tweaked Plasma Renderer, by using OpenGL for the backend the Threaded for Loop, Plasma Shell still crashes, but it reloads this time around.

Spoke too soon

It seems that the crash mainly happens after I switch to a different activity the first time, but it doesn't seem to happen (or happen much less often) the second time and onwards.

At the moment this is just a hunch, but I noticed that any activity that has a slideshow enabled as a wallpaper will cause Plasma to crash, even if it's for a single monitor.

I filed bug 413068 earlier (lock screen crashes with slideshow wallpapers).  What are the chances they are related?
