Basically we have to disable 3D Acceleration and switch to VBoxVGA as the graphics controller.
Also just a note about shared folders.

It seems that it can be possible to re-enable VBoxSVGA, if we install the latest guest additions inside the VM. But it's not really important, I only use it to do the accounting software.
