Every state update from Dart reloads the native member picker, which built fresh cells showing the initials fallback and fetched each avatar again over the platform channel, so avatars blinked whenever results refreshed, most visibly right after foregrounding. Keep loaded avatars by key and draw them at once when a cell is rebuilt.
