Description

Go to https://www.gradientmagic.com/collection/experimental/gradient/1584201794532

AR: The gradient is rendered differently in Nightly.

I dont know what should be the correct rendering, so feel free to resolve as WONTFIX or INVALID.

:nical, since you are the author of the regressor, bug 1888628, could you take a look? Also, could you set the severity field?

In this case the way the gradient is rendered is actually more correct after the changes thanks to it being rendered at the correct resolution. It also looks closer to how chrome render it.
