I have searched and found the VirtualBox Guest Addons fix, but that isn't working for me. Every time I resize the window in the VirtualBox settings and/or the Display Settings in Parrot Security, it initially resizes to what I want but reverts back to the 800x600 square default (both the VB machine (if in scaled mode) and the Parrot Sec display, although the display settings still say that they are in the higher resolution - see the screenshot below which shows a VirtualBox screen expanded to fit my display, with a Parrot Sec display resized to 1280x800 but only showing as 800x600. If I click where my mouse is in the screenshot, the window briefly goes to 1280x800 only to drop back to 800x600 a fraction of a second later.
