I set my watch to display pixel ratio in aod mode and it works for all watch apps, except with cairo based watch (watch cairo and watchcairoevasgl sample app). With cairo apps nothing is displayed in aod mode and no pixel ratio info is shown.
It seems the reason aod not working because both watchcairo and watchcairoevasgl exceed the 15 % ratio. Once I set the background color to black the aod watchcairo run as expected.
The watchcairoevasgl still doesn’t work on aod mode, my guess is in aod mode hardware acceleration is turned off.
