Hi @Philip Lind,
Based on my test this should be the expected behavior.
As in Teams recording it records the Teams meeting window (including the attendees) rather than only the screen you are seeing.
That is why changing the view to Focus on the content, which is a user-side setting**,** does not affect what contents are recorded.
Here are also some related Teams Uservoice threads:
Can we please edit participants view from Recorded Sessions
Request to provide setting to allow full screen recording without profile picture.
If you would like to submit your feedback to Microsoft, please consider upvoting or leaving a comment.
And if it is possible, I would suggest using some third-party recording tools instead to custom the recording area as a workaround.
