Extremely high CPU/GPU usage because of Canvas Scene

[taesungh]

Unsure if this is just my machine, but the entire site consumes a lot of resources, even when the Fireflies are removed, because of the Canvas Scene.

The timeline profiler in Safari shows near 100% CPU usage because of requestAnimationFrame timers happening in some loop function inside createLoop. Activity Monitor shows high GPU usage (around 50%) instead of CPU. I can audibly hear my GPU fans ramping up to 2000 rpm when the site is open and doing nothing.

Don't really have this issue on Chrome.

Safari 16.6 on macOS 12.6.9 with Intel processor, AMD Radeon GPU.
Tried with both Develop > Experimental Features > GPU Process: Canvas Rendering enabled and disabled.
