On the top is my KDE neon virtualised on a Win10 host (virtualbox), I have just update KDE neon and in the same time, update Virtualbox installation to the latest one (6.0.22.x). What is the problem? I have no acces to the buttons on the bottom the KDE neon windows like you can see. I don't know, finally, if it is a KDE neon problem, or a Virtualbox error. I have the lastest guest-addons installed too.

Thanks for any help.
//EDIT : I add somethings too. My host as a 1920 * 1080 px resolution. In my guest, I had a 800 * 600 resolution, but with steamless the VM occupied all the rest of the resolution my host leave, minus the height of the taskbar. So I had no problem until the Virtualbox update this afternoon. The VM was redimentionned to 800 * 600 instead to occup all the free space, so I have to play with the resolution in the guest. So I ask just want I should do to retrieve the comportement I had in my VM.
