Size is too large:

Intended size:

Note that first screenshot was taken before this commit d95df33cfd3fd9380b6e269b63a50d456de09422 So size is even larger.

Icon is two times bigger than intended size.

See this function: MoveItem._get_item_cursor_icon()

Dividing by value returned from DisplayServer.screen_get_scale() appears to not help.

I'm experiencing slightly different behavior with the dragged item now:

1. Click on an item in stash
2. It shows this big icon of the item
3. When I start dragging icon disappears (it may disappear a second after I start dragging)
4. Item is still dragged so I can click on a tower and item will be transfer from stash to that tower (so only visual part is not working correctly)
