What's the problem? Describe what went wrong.

Emulator is extremely slow (<1 FPS) on macOS Mojave DP2 only if the game window is focused

What steps will reproduce the problem?

  1. Open a game
  2. Game will run extremely slowly
  3. Change focus to a different window
  4. Game runs at normal speed

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.

Yes, 5.0-8199 (77f6e50493c0433391a4da1815b09d85d1a36247)

Is the issue present in the latest stable version?

No, but game runs at 5 FPS anyways

If the issue isn't present in the latest stable version, which is the first broken version? (You can find the first broken version by bisecting. Windows users can use the tool https://forums.dolphin-emu.org/Thread-green-notice-development-thread-unofficial-dolphin-bisection-tool-for-finding-broken-builds and anyone who is building Dolphin on their own can use git bisect.)

5.0-6235 - broken
5.0-5636 - broken
5.0-4994 - broken but less broken?
5.0-4298 - I can't tell because performance is already 2 FPS

What are your PC specifications? (CPU, GPU, Operating System, more)
- MacBook Pro (Retina, 13-inch, Mid 2014)
- 2.6 GHz Intel Core i5
- 8 GB 1600 MHz DDR3
- Intel Iris 1536 MB
- macOS Mojave 10.14 Beta (18A314h) = Developer Preview 2

Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)

When I disconnect all controllers, focused performance is more like 6 FPS instead of 0 FPS.
