Now I wonder if apps themselves could tell the OS that the entire browser window was DRM content and avoid being scanned by Recall.

@bigolewannabe not trivially - the client would need to encrypt the window content and pass it through the DRM rendering API

@RnDanger @bigolewannabe The least restrictive Widevine is implemented in Javascript and doesn't require GPU involvement so can be captured, and it's only fairly recently that Firefox got full Widevine support

@RnDanger @mjg59 @bigolewannabe a lot of DRM content on the web you can still record by turning off "hardware acceleration" which makes the player use JavaScript instead of the GPU so it can't be DRMed
