Normal Canvas : https://share.firefox.dev/3O3QBEh
Accelerated Canvas : https://share.firefox.dev/3mZX0EN
FWIW, the profile with gpu-canvas appears to be busier in the content-process compared to the unaccelerated-canvas profile

These pages are quite weird.. Sometimes they will OOM just by opening them in a tab. Other times, I need to zoom-out by 30% before they start to OOM.
This random behavior persists across new profiles and browser restarts
Edit: A nightly from January (with gpu-canvas enabled manually) also reproduces this behavior. This is strange because I am pretty sure i have tested this demo earlier and the bug didn't repro.

Fixed by bug 1793769
Bug 1793769 - Avoid recreating the main DrawTargetWebgl SharedContext. r=aosmond
For canvas users that rapidly create and destroy canvases, we may end up creating
a new SharedContext (and hence ClientWebGLContext) if there are no more canvases
left between destruction and creation. To work around this, just keep alive the
SharedContext for the main thread (other threads are unfortunately a bit tricky
to support) so that canvas creation remains fast in this instance.
