            Bug ID: 233729
           Summary: WebGL Poor performance on block.xyz
           Product: WebKit
           Version: Safari 15
          Hardware: Unspecified
                OS: Unspecified

The animated cube in https://block.xyz/ does not animate smoothly in WebKit using WebGL 2. The animation playback + rotation interaction is smooth on both Firefox and Chrome. The performance improves if you enable "WebGL via Metal", but it is not as smooth as in other browsers.


Other information:

- I tested this on a 1920x1080 monitor with STP 135
- I am using a 15 inch 2016 MacBook Pro with the following graphics cards:
  * Radeon Pro 455 2 GB
  * Intel HD Graphics 530 1536 MB
