Subject: [PATCH] ZeroHertzAdapterMode: turn default on.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Field telemetry has shown the combination of min_fps = 0 and max_fps >
0 is unused in the wild. Therefore it's safe to turn the
WebRTC-ZeroHertzScreenshare field trial default on unless the field
trial is disabled.
