Reported memory usage doubled in 6.1.4 on MacOS Mojave and later

we recently noticed that memory usage doubled on Catalina (confirmed on 10.15.5). Upon investigating the problem we figured out that this issue began with 6.1.4. The problem is still present in 6.1.10.
Up until 6.1.2 memory and real memory were basically the same. Allocating 4GB in the VM resulted in a memory usage of 4GB.
From 6.1.4 onwards, memory is always twice as large as real memory:
- allocating 4GB results in 8GB being used
- allocating 8GB results in 16GB being used
and so on (see attached images)
Reverting back to 6.1.2 fixes the problem. We couldn't find a bug report about it, but we did find a few reports on the forums:
It's possible this bug might specific to Catalina, as I personally only noticed running out on memory after upgrading from Mojave. I think I was already on 6.1.4, but I don't have a Mojave machine so I can't test this theory.
Everyone in our development team had to install 6.1.2 because we generally allocate 8GB to the virtual machine, which ended up using 16GB. As most of us have 16GB of ram, this made our machines unusable.
