macos fn becomes stuck (mac -> mac)

[bilogic]

Bug Description

When connecting RD1.2.3 from mac to mac, the fn key often becomes stuck. If the controller side presses c, it becomes fn + c on the controlled side, cause the command center to launch.

How to Reproduce

Unsure exact steps, but both machines were macos

Expected Behavior

fn should not be stuck, pressing c should send only c to the controlled side.

Operating system(s) on local side and remote side

osx -> osx

RustDesk Version(s) on local side and remote side

1.2.3 -> 1.2.3

1.2.2 does not? How to reproduce?

[bilogic]

I'm not sure, I was on 1.1.9 connecting to 1.2.3, then I tried 1.2.3 to 1.2.3. I can try 1.1.9 to 1.1.9 tomorrow. First time connecting from mac to mac. Unsure how to reproduce, but the way to fix it was to disconnect and reconnect immediately. We are using VSCode over RD, so pressing a lot of shortcut keys, e.g. cmd, option, shift and control, then suddenly strange things happen when we press alphabets only, e.g.

1. fn + d = dictation
2. fn + f = full screen
3. fn + c = command center
4. fn + h = hide all windows

That's how we figure out that fn key was stuck

[rustdesk]

have to move to #4367 since it is hard to reproduce.
