Different behavior when creating png files with Firefox/Chrome

[Stefan Lorenz]

Hi,

I have a issue with Firefox and Chrome when generating an image file from d3js...

In Chrome the gradient looks exactly like the one from d3js but in Firefox the gradient is not visible (like in the pictures below).

I have no idea where i could begin to fix this or what is causing this. The Javascript code is always the same and the browsers are up to date.

Does anyone have a hint for me?

You can try it by yourself if you want to: https://gpxviz2.sisao.de/
