How is your computer connected to the output screen(s)? DisplayPort * 3, HDMI
Description of the bug: When showing PowerPoint files, the Alpha Channel is not filled with white color.
How was your service impacted? The streaming producer must know when I show PowerPoint files and then use another key on the video mixer for that.
How was your preparation time impacted? -
Step by step instructions on how to reproduce the bug: 

Turn on Alpha Channel in Main Output in Options or turn on Alternate Output with its Alpha Channel.
Put a PowerPoint in the schedule. Go live. The Alpha Channel monitor is black instead of white.

It works with a song, a scripture, a video or an image. The Alpha Channel monitor keys it out in white when I go live.
PowerPoint works with EasyWorship 7.4 on the same computer. I use an updated Office 365.
