Im in talks with Microsoft and AppleCare right now. They are both aware of the issue. According to apple, it is a isolated incident.
I urge you to contact Microsoft and AppleCare. I personally emailed the CEO of Microsoft and called apple care.
Please record every time it flickers and then call AppleCare so they can send you a link to submit the videos. Do provide details of when it occurs, what slides it occurs with, and the date and time.
This is what I sent to both Microsoft and AppleCare:
Hope all is well! The issue with power point occurred again on Thursday and Saturday night. Attached to the email are videos. Disregard the voices in the background as I was in class when it occurred. Hope you find them useful.
For IMG_4303.MOV and IMG_4304,MOV, it occurred on Thursday, March 09, 2017 at around 7 pm. I have attached the slides Chapter 6 textbook slides.pptx) I used for class. I assumed this problem only occurred with this publisher's ppt but than
it occurred on today, Saturday with a different set of ppt.

 IMG_4304.MOV
On Saturday, March 11, it problem persisted. I have attached IMG_4318. I opened up my intermediate accounting ppt to look over my notes when the problem occurred. To me, it seems like every time I open up my slides my screen flickers so I did
some work and I hope you find the information below useful. IMG_4321.MOV is about 5 minutes long:
The first 3 minutes show my ppt for chapter 5 when the flickering gets progressively worse, I closed the ppt. I then open my Fed tax ppt (see attached) and the problem was still going on (3:20 to 4:20) so I closed that one and opened up a another
slide created by my professor (4:21 - 5:10, see attached) and the problem didn't occur. Based on my analysis, it seems to me that the flickering occurs when viewing large sized ppt files. The one I showed you was a relatively small sized file. I am on break
from school so any time after 1 pm EST, except Thursday, I am available to talk on the phone.
Hope this helps!
