--- Comment #2 from michael.hubbard...@gmail.com ---
Hello Juan,
Thanks for this detailed message!

I normally dig into release notes before opening a bug. 

I just found them in the screen with the open button. I see now that this is
known behavior in Ubuntu 20.04.

I do have a System76 Gazelle with Kali rolling, I will try it that machine.

I will let you know what happens!
