Component: application
Assignee: mvourla...@gmail.com

When using some particular combinations of plasmoid with a "(panel) latte dock"
latte dock regularly freeze and need to be killed / restarted so it works
again.
Also, promoting a dock to panel then removing its latte plasmoid, always lead
to freeze, ie a plasmoid latte dock less panel always freeze.
STEPS TO REPRODUCE
1. Create a new user
2. Log in with this user
3. You should arrive on a plasma having a bottom latte dock
4. Create a top panel dock
5. Add 2 or 3 web browser plasmoids
6. Add system tray (or notifications) plasmoid
7. Open the web browser plasmoid popup
8. Use kde shortcut to resize / move windows: Meta+ Up/Left/Top/Bottom
9. Notice after the second shortcut trigger the popup does no longer render
correctly
10. Try to use your panel / dock
11. It's not working, it's frozen
OBSERVED RESULT
Latte dock freeze
EXPECTED RESULT
No freeze
