Makehuman makes my desktop taskbar vanish (linux, MATE desktop)

[SuperUserNameMan]

System : Linux Mint 21.1 with MATE desktop

Makehuman : git clone of master branch from here

Each time i use Makehuman, after a few seconds, my desktop taskbar becomes invisible, and i can't disconnect from my session, nor reboot the computer.

After a mate-panel --reset in terminal, it stopped doing that. Maybe there was a bad interaction with something I added to my taskbar.

nope, it still do that again randomly
