I recently turned on Color correction on my Pixel 7a, and noticed that some youtube videos viewed through the browser caused the system bars to gradually brighten over about 1 second, which is distracting. The brightness stays this way until navigating away from the page, after which the brightness will dim back to normal over about 1 second.
This looks like a bug with displaying SDR UI together with HDR videos and images. Turning Color correction on seems to trigger this bug in Vanadium and Brave browsers. Other apps like Google Photos instead display HDR content in SDR when Color correction is on.
Steps to reproduce:
- On Pixel 7a with Graphene OS installed, with color correction off, open Vanadium and navigate to a web page with HDR content such as an HDR youtube video or https://www.wide-gamut.com/test/image-hdr . The HDR content should brighten over 1 second and the system UI should stay the same brightness.
- Open Settings, navigate to Accessibility > Colour and Motion > Color correction, and toggle Use color correction to on.
- Return to the web page with HDR content.
Expected: The HDR content brightens over 1 second and the system UI stays the same brightness, like it did when Color correction was off.
Actual: The system bars brighten along with the HDR content.
Is this a display bug in Graphene OS or is it an issue with Chromium or AOSP?
