[Software] Desktop panel bar all filled with trash

[avicenna]

My Debian 12 system seems corrupted after running a downloaded program (not install from apt or snap).

The top panel bar has many panels opened; don't know how it happened. How do I removed them all?

Which non-standard program are you running?
Which desktop do you use? GNOME? MATE? Cinnamon? KDE? XFCE? LXDE? LXQt?

I use mate desktop for years; no problem ever.

program is Banksia chess GUI. Don't know it if was the problem; just many
apps opened right blocking the left hand app/places/system choices.

Just had to manually remove all (about 20+ panels) . "Solved"

Thanks.
