Focus Follows Mouse Not Working With Multiple Displays

[mfickett]

Describe the bug

When an external monitor is connected to my MacBook Pro, focus follows mouse does not work at all. As mentioned in https://github.com/ianyh/Amethyst/issues/798#issuecomment-469764459 (but that's mostly about fullscreen windows which I'm not using).

Applications: Tried with: Google Chrome, Finder, Activity Monitor.

To Reproduce Steps to reproduce the behavior:

1. Connect an external 30" monitor.
2. Open 2x Chrome windows, 1x Activity Monitor on the laptop's monitor.
3. Open 2x Chrome windows, 1x Finder on the external monitor.
4. Enable focus follows mouse in Amethyst.
   • Expected: Mousing over windows focuses each window.
   • Observed: Mousing over windows does not change focus.
5. Disconnect external monitor. (Do not relaunch Amethyst or change settings.)
   • Observed: Now mousing over windows changes focus.

Versions:

• macOS: 11.2.1
• Amethyst: 0.15.4 (91)

@mfickett AutoRaise implements this well. Can we use this code?

Got the same problem. Focus Follows Mouse was one of the main reasons for installing Amethyst. Coming from Linux to Macos this is the cause of much frustration and pain. Please, please move this bug up the priority list. I keep copying and pasting wrong things since i forget that i have to click 2 times on a window in Macos.

Same problem for me... Any update on this? :)
