Comment 5 for bug 1655694

Object triggering the rendering artifacts:
path6629, path5971, path5971, path6043

They all reference the colors of the black-to-transparent gradient 20164-7, and use specific gradientTransforms like

matrix(0,0.02492168,-8.3771866,0,3756.8234,-488.45524)
matrix(0,0.02492168,-8.8644754,0,4041.0118,-443.92787)
matrix(0,0.02743499,-4.5080969,0,1481.4226,-420.64502)
matrix(0,0.02293027,-2.0801871,0,54.4486,-411.21809)

Removing the paths, or changing their fill to a solid color (for testing) makes the artifacts go away. When the gradients are re-applied after that, they will no longer expose these rendering artifacts because the gradientTransform will be optimized into the coordinates of the gradient vector.

These artifacts with transformed gradients using very small dimensions has been reported before and is tracked in
