  • Many sites online take advantage of Hardware Acceleration for interactive elements; from productivity sites like Mixamo to games websites such as Club Penguin Rewritten. However, Hardware Acceleration can sometimes break the experience on certain sites when another accelerated application is running in the background, with the most notable example being Youtube having severe playback issues when it has to share resources with other applications such as Discord or some PC games.

    Because of this, it would be good to have a blacklist feature for Hardware Acceleration. This would allow the user to keep it enabled in their browser, but stop it from working on specific websites, meaning a user doesn't have to relaunch the browser every time they want to change the setting.

    There are some flags currently available for the user to block certain categories of Hardware Acceleration, but in my experience these are simply not enough. The descriptions are too unclear to tell exactly what is being changed, and sometimes a flag that looks like it should stop a certain website from using Hardware Acceleration doesn't work at all (Youtube, for example, still experiences the same playback issues even when the Hardware Accelerated Video Encode / Decode flags are disabled.)

    A blacklist feature would not only help to fix some of these performance issues, but would also make the specific websites that can use Hardware Acceleration much clearer to the user.
