Mouse clicks and scroll wheel stop working in VirtualBox and parts of the system when going fullscreen

[MexIT]

Mouse clicks and scroll wheel stop working in VirtualBox and parts of the system (e.g. Firefox) when going fullscreen. At the same time, in terminal and Thunderbird, clicks work properly. I noticed that the virtual machine icon disappears from the dock panel.

Host: Ubuntu 22.04 Guest: Win 11, Manjaro, ...

The keyboard works properly. After closing the VirtualBox window with Ctrl+q, mouse clicks are possible again

Below are the logs from when the problem occurred:
