A repeated chooser can be expected
A browser asking which window or display to share again may be following the capture model rather than forgetting a saved preference. MDN documents that permission for the web getDisplayMedia capture API cannot be persisted for reuse. The user must make another permission decision for a new call.
The current source matters
A display can contain different windows and notifications from the last session. A new chooser gives the person a chance to select the minimum useful surface again. Do not rush through it merely because a prior support session used the whole desktop. Read the actual selected source and recipient context.
Audio is a separate variation
MDN notes that audio support and available capture sources differ by browser. A previous session containing sound does not guarantee the same result in another browser or source choice. Check the options presented and use a short harmless example instead of assuming that the microphone and system audio are interchangeable.
Avoid removing protections to stop prompts
An expected permission decision is not a reason to disable browser security globally or install a tool promising permanent silent capture. Use the trusted site’s documented flow, preserve a visible sharing indication and stop the session deliberately. Minimising a window is not proof that capture ended.
Report an actual failure distinctly
If the chooser does not appear, the selected source fails or the browser refuses the action, describe that state and the browser version. A new prompt after a completed session is another observation. Keeping those cases separate prevents expected capture permission from being misdiagnosed as a broken account or a failed remembered setting.
Questions, answered
Can this web capture permission be silently reused forever?
No. MDN documents a new permission decision for each call.
Does another prompt necessarily indicate a fault?
No. Repeated source selection can be expected behaviour.
