Thank you! Canvas performance is on the radar of the graphics team and we expect improvements there next half, though I of course can't guarantee they will fix this particular case. But it gives us insight which issues people hit in the field.

AFAIK one known performance difference here is that we use software rendering on macOS, and Chromium/Safari use HW acceleration there. The latter isn't necessarily always faster, and it might be irrelevant to this problem, but differences in behavior aren't unexpected. We probably don't want to be 10x as slow though.

Edit: feedback from gfx is that this indeed something they expect HW acceleration would improve
