With GPU-canvas, this is quite smooth : https://share.firefox.dev/3BC7OA1

:lsalzman, can you comment to the bug?

Most of the time appears to be spent waiting on a round-trip because of webgl.out-of-process.async-present.force-sync. That means are dependent on the completion of bug 1776885 to address this.

With GPU-canvas / D2d-Canvas, the demo is not as smooth as Chrome : https://share.firefox.dev/47gHCKu

The last two profiles show that the 2D canvas doesn't end up being an accelerated canvas, the fillRect is done using skia and the texImage2D is doing a memcpy.
