Description

[Mayank Bansal]

Go to https://codepen.io/DonKarlssonSan/pen/LYzBYEP

Skia-canvas + async: https://share.firefox.dev/3KWFRaO (feels very smooth)
Gpu-canvas+ async: https://share.firefox.dev/3GXLggu / https://share.firefox.dev/41mZuj3 (feels very janky)

skia-canvas + Sync: https://share.firefox.dev/41Cxk3k (feels very smooth)
gpu-canvas+sync: https://share.firefox.dev/3A7DMUp (feels very janky)

I am filing this separately from bug 1804447. This bug is specifically for gpu-canvas VS skia-canvas.
Feel free to dupe as you see fit.

Hi Lee

With the latest Nightly, here is a profile : https://share.firefox.dev/3LmaBn1 (Codepen version) / https://share.firefox.dev/426a7ab (local version)
With gpu-canvas, subjectively the demo still feels much more laggy as compared to skia-canvas.
