Why does a USB webcam flicker only on video calls with screen sharing?
Our answer
Switch the camera power-frequency setting between 50 and 60 Hz and disable auto-exposure; check hub bandwidth during screen sharing.
Why this approach makes sense
Device software, permissions and connected services change how a feature behaves; use settings for the actual model rather than a generic workaround.
Before you try it
Verify the relevant device and account permissions, and make changes one at a time.
