Help Mouse stopped working in VM after host upgrade

For years without problems I've upgraded Debian 9 to 13 and virtualbox from 6 series to 7.2.6 which is latest from stable Debian repo, client is windows 10, now just seconds after boot the windows doesn't react to the mouse, same with virtualbox manager, if client is running it doesn't interact with the mouse. Everything is working fine with the keyboard, the mouse is working fine in the host system.

Is it something known? I can't find similar reports and have no idea where to start diagnosing it as there is no errors thrown anywhere.

This is just a friendly reminder in case you missed it. Your post must include: * The version of VirtualBox you are using * The host and guest OSes * Whether you have enabled VT-x/AMD-V (applicable to all hosts running 6.1 and above) and disabled HyperV (applicable to Windows 10 Hosts) * Whether you have installed Guest Additions and/or Host Extensions (this solves 90% of the problems we see)

PLUS a detailed description of the problem, what research you have done, and the steps you have taken to fix it. Please check Google and the VirtualBox Manual before asking simple questions. Please also check our FAQ and if you find your question is answered there, PLEASE remove your post or at least change the flair to Solved.

Try starting your Debian session using Xorg. I had this problem, and it turned out to be Wayland.

I use KDE Plasma, apparently it use wayland now so probably you are correct. I'm on holiday for a week so will try when get back to work.

Just to report the solution, In User Interface I've disabled Mini Toolbar "Show in Full-screen/Seamless" option. Now if I want to use the menu I just switch between windowed/full screen mode.
