MAC: Mouse input does not aligned with the cursor when switching from windowed to fullscreen

Mouse input is not aligned with the visible cursor when users switch from windowed to fullscreen. Input seems to be located to the left of the visible cursor. This prevents users from accessing any of the menu options top right of the screen.

WORKAROUND:
Use console command "setres 1280x720w". Users will then be able to open the settings menu and change the resolution.

STEPS:
1. Launch game client on cooked build 2581909 in windowed 1280x720.
2. Open settings menu and change to fullscreen.
3. Apply settings.
4. Move mouse cursor over the top menu observing input location.

RESULT:
Mouse input does not align with the cursor.
