Detailed Issue Description:
When taking a realms feed screenshot, there is visual fragmentation occurring at the top of every screenshot (roughly 5% of the top of the photo is distorted). Once shared to the feed, it still exists. 

Note:
It is also not possible to view in detail on the Xbox app, however feed screenshots posted via PC are viewable - I've attached screenshots to this ticket for what is displayed when trying to view the image in detail (i.e. non-thumbnail view)

Note (Update):
The screenshots posted by other players with this visual distortion cannot be viewed from the feed in the Xbox app. Only the photos you post. See attachments.

Steps to Reproduce:

1. Log in to a realms server
2. Take a "Feed" screenshot via the pause menu
3. Post the image to the Feed
4. Review the photo in the Feed

Observed Results:
Photo has visual fragments/artifacts distorting the top of the screenshot.

Expected Results:
Photo should match what the player saw without issues.
