I can imagine some confusion, so we can also try to make it easier to understand. For example, "scale display" and "resize desktop" are perhaps better naming. Adding a tooltip could also help, with explanations like "Scales the local display" and "Changes the remote desktop resolution".
The alternative is to remove it from the menu, and just have a command line argument --no-scaling, ?
