VirtualBox is a dumpster fire
>I'm currently struggling to run Linux Mint as a VM under a Windows 10 host using Virtual Box
Assuming if its for work then your employer is cheap if you are using Virtual Box. Linux Mint also is not an ideal choice for say a server VM. As for your problem I have seen that same thing before and it was a VirtualBox issue not OS. Going to get down voted but VirtualBox is garbage and should only be used if you have no other choice (like us BSDers). It's buggy and its performance sucks in general but its windows guest performance is especially abysmal. If you need to get real work done you are much better off with VMware even if its just the player.
