Does the same occur with vanilla, non-Staging Wine?
I tried a while back and it did. The interesting thing is, the problem got fixed like 6 patches ago.
It now eats a lot less ram. Its at most using 5. And I upgraded my ram to 32GB.
When I first got 32GB it was eating like 12GB or something.
So I guess this is fixed for now.
