Problem
I was in a meeting on Microsoft Teams when I shared my screen it had serious constant flicker which not only I see but other persons also were able to see at other ends. I was working on Windows 10 with Microsoft Teams app.
Reason
It was due to the sharing of the screen under the category WINDOWS.
Solution
The screen sharing option shows many tiles to share. These tiles come under two categories Desktop and Window. Make your selection for the screen you want to share under Desktop not Window. This selection made my screen not flicker anymore.

If it has option to share Windows why it should flicker? This cannot be considered as a solution for the issue.
