Q: Disable Automatic Menu Dropdown in Full-Screen Apps

I am using Splashtop and I am looking into streaming games from my gaming PC over onto my Mac. For those who think this is a bad solution, I have tried the following:

- Hosting a VPN connection on my PC so I can connect to it while I am outside on my Mac. Therefore tricking Steam to let me "In-Home Streaming" while my Mac is outside. However, I could not find what the "Shared Secret Key" is (please tell me what this is anyways, thanks)

- Using Moonlight/GeForce streaming and port forwarding to play on my Mac. While this does work at home, it fails when I am outside on both my iPhone and Mac.

- Using VMWare, too laggy...

- Using Bootcamp, too laggy...

- Using Parallels, too laggy...

So Splashtop is my current solution. However, when I play a game, the top menu bar of my mac keeps dropping down when I move my mouse upwards during a game. This is now getting on my nerves as I have tried over 4 solutions and none of them seems to work.

I have tried doing this:

However, when I change the "Normal" value to "All Suppressed", it just auto reverts itself.
