Description Piotr Porada 2017-09-02 15:58:29 UTC
Black-out and white-out functionalities do not work properly on macOS Sierra.

After entering fullscreen presentation mode with secondary monitor attached primary monitor shows presenter console and secondary monitor shows current slide. Black-out and white-out shortcuts do not work unless I click directly on the slide on the secondary monitor.

Problem occurs only on macOS. Tried the same version on a Windows PC and it worked correctly

Steps to Reproduce:
1. Open a slideshow with two monitors attached
2. Enter slideshow (eg. F5)
3. Press B or W key

Actual Results:  
Nothing happens unless the slide on the actual slideshow is clicked

Expected Results:
Actual slideshow is blacked-out (B key) or whited-out (W key)

Reproducible: Always

User Profile Reset: Yes - started in Safe Mode, problem still occurs

Additional Info:
Computer affected is a Macbook Air 11" (Early 2015) with up-to-date updates installed

The other computer I tried is a Lenovo Y50-70 with Win 8.1 (from factory image) also with up-to-date updates installed.

Problem occurs regardless of which slideshow is opened.
