Summary: Desktop Cube effect stops working after using the
overview/grid effect or after triggering it 5 times
Classification: Plasma
Product: kdeplasma-addons
Version: git-master
Platform: Compiled Sources
OS: Linux
Status: REPORTED

SUMMARY
With Plasma 6 compiled from git master using kdesrc-build, I noticed that the
Desktop Cube effect stops working after either opening it about 5 times (in
other words pressing its keyboard shortcut 10 times or so) or activating the
overview/grid effect and then closing it.
When the effect is no longer working, I see this message appear in the system
logs after every second press of the keyboard shortcut (so when the effect
would be closed if it was working): "QuickSceneEffect.source is empty. Did you
forget to call setSource()?"
STEPS TO REPRODUCE
1. Open the overview/grid effect and close it
2. Try to open the desktop cube effect
OBSERVED RESULT
The desktop cube does not appear on screen
EXPECTED RESULT
The desktop cube appears on the screen
