Panels that constantly unmask

Hello everyone.
I have two panels that I have set to hide automatically.
Except that both unhide themselves as soon as anything happens in KDE.
To hide them again, I have to click on each of the two panels.
New window, hop, the panels are displayed. Window closes, hop, panels appear. If I maximize or minimize a window, the panels are displayed. Exit full screen, hop, do it again. Change window, hop, panels appear. A pop-up window, always the same scene.
It’s extremely annoying and I don’t know how to deactivate it.
The task manager’s “Unmasked when a window reports” option is disabled.
This is going to drive me crazy.
Especially as I don’t understand the point of such behavior.
If someone could help me to solve this?
Thanks in advance.
