Open the attached SVG in nightly and scroll
ER: Smooth scrolling
AR: Janky scrolling
This has bug 1681921, which enabled sw-wr on small devices.
With D3d11, the scrolling was quite smooth and there was no checkerboarding.

Could you please attach the about:support from the last good build? Your about:support indicates you get hardware webrender, so it's unlikely bug 1681921 changed anything.

I wasnt clear here.
Before bug 1681921, I had D2d11. With bug 1681921, I got sw-wr. And somewhere from there, I got hw-wr.
The switch from d2d11 to WR (sw or hw) made scrolling SVG bad.

Looks like some big spikes in blob rasterizations.
