(Quick-note) How to fix Virtualbox 7 screen turning black when on fullscreen (or above a specific screen size) on Windows 11

Context

I have a VM (Virtual Machine) with Ubuntu 22.04 running on VirtualBox 7 on Windows 11. Every time I made the VM screen bigger, at some point the whole VM screen turned black. This also happened when on full-screen.

Solution

You just have to increase the memory of the virtual graphic card to 128 mb. For this the VM should be off (no just suspended) You can also activate 3D.
