one hint from my side...I used unclutter on raspbian buster to hide the mouse pointer. I did not directly recognize, but indeed after using unclutter lxpanel also had ~100% cpu usage. Somehow they disturb each other.

I simply uninstalled unclutter and did hide the mouse pointer by another method:

    sudo nano /etc/lightdm/lightdm.conf

    changed:
    # xserver-command = X

    to:
    xserver-command = X -nocursor

and lxpanel had nicely a low cpu usage again.
