Hello
I found a very strange issue on Virtualbox 6.1.14 running on Ubuntu 18.04 host, Debian GNU/Linux bullseye (testing) guest using Gnome 3.30 desktop (or KDE Plasma 5.17) and a Logitech HD webcam C270 on fullscreen VM.
If enable webcam device on virtualbox toolbar, the keyboard is lost.
It also happens with Debian GNU/Linux 10.5 buster VM.
BUT this problem does not happen when using windowed VM.
What additional info should I collect to submit a bug report?
Regards.
Andre Felipe
