Public bug reported:
Bluetooth panel is using ActvityIndicator (i.e. spinner) while it is
scanning for new devices. It stays running for 30 seconds, then turns
off for ~10 seconds, then runs again. Each time it runs is causes ~50%
cpu usage on unity8 (no fault of system-settings).
This is a potential big problem on on pocket desktop, as you have to
open the bluetooth panel to pair, then typically it will stay open in
windowed mode and will cause a big battery drain as the window is
visible in running.
Until the cpu usage issue is addressed in unity, we should not use this
component. Instead, how about just show text "scanning..." or
"searching.." as the first list item or where the spinner currently is.
