1041677 - reposition the global webrtc sharing indicator if the screen resolution changes

Status: NEW

(Firefox :: Site Permissions, defect, P3)

Description

[Florian Quèze [:florian]]

I suspect the global sharing indicator that landed in bug 1037408 may end up displayed at the wrong position if the user plugs/unplugs an external screen, or if the screen resolution is changed.

This is kind of an edge case, but it would be nice to verify how bad the current behavior is there, and if there are easy ways to improve it (I'm not aware of any event or notification fired when the screen resolution changes, but that doesn't mean there isn't one).

I'm not sure this is a significant enough concern that we should prioritize it right now.

Anyway, as best I can tell, stuff disappears offscreen (bad), but equally, there are no events that tell you about resolution changes. Any such code would probably want to live in nsScreenManager, and be platform-specific.

We could possibly hack around by just checking every 5-10 seconds or so that we were still inside the screen rect?

Gavin, this isn't really actionable until bug 1055617 is fixed - can we remove it from the backlog, please, and/or add that one? Thanks!

I'll mark it as blocked.

We no longer show the legacy WebRTC indicator on Windows or macOS, but this still affects Linux.
