Big Sur in Virtualbox blank maps

Hey

I successfully installed Big Sur inside Virtualbox on my Linux (Arch btw.) machine. There is no problem with the software I tried and I connected it to my Apple account without a problem.

When testing the software I want to use the VM for (OpenHaystack) I encountered a black/blank map view with only the map markers showing up. No difference in Satelite or Map mode.

I tried opening the standard "Maps" software after this and had the same issue with a black/blank view.

Screenshot (i added the red boxes)

I used the following commands to set up the VM parameters according to some guide on the internet:

vboxmanage modifyvm "macOS1" --cpuidset 00000001 000106e5 00100800 0098e3fd bfebfbff

vboxmanage setextradata "macOS1" "VBoxInternal/Devices/efi/0/Config/DmiSystemProduct" "iMac19,1"

vboxmanage setextradata "macOS1" "VBoxInternal/Devices/efi/0/Config/DmiSystemVersion" "1.0"

vboxmanage setextradata "macOS1" "VBoxInternal/Devices/efi/0/Config/DmiBoardProduct" "Mac-AA95B1DDAB278B95"

vboxmanage setextradata "macOS1" "VBoxInternal/Devices/smc/0/Config/DeviceKey" "ourhardworkbythesewordsguardedpleasedontsteal(c)AppleComputerInc"

I tried all the different graphicscontrollers available in virtualbox with no difference.

vboxmanage setextradata "macOS1" "VBoxInternal/Devices/smc/0/Config/GetKeyFromRealSMC" 1

Any idea how to fix this?
