Use latest nightly on Windows.

Set the following prefs
gfx.direct2d.disabled = true
gfx.canvas.accelerated = true
gfx.canvas.remote.worker-threads = 0 
Go to codepen.io/KilledByAPixel/pen/WNQoMYg

AR: The browser freezes and the demo is very slow to run.

Regression range:
Bug 1829026 - Handle KERN_ABORTED from semaphore_wait. r=aosmond
Differential Revision: https://phabricator.services.mozilla.com/D195952

Note that the performance regressed for both GPU-canvas and d2d-canvas. With skia-canvas, it runs absolutely fine. I have not filed any bug for d2d-canvas. Let me know if needed.

Note that the performance regressed for both GPU-canvas and d2d-canvas, but gpu-canvas has a much worse regression. With skia-canvas, it runs absolutely fine. I have not filed any bug for d2d-canvas. Let me know if needed.
