In the URL you can see we use several SVG elements in a page to draw gauges.
We use Bootstrap carousel to show and hide several other gauges (a drill-down).
After some play with clicking on the big gauges all the SVG elements in the screen become partially black.
The exact same behavior happen use we use simple CSS change of display:none and display:block.
Also the same behavior happen when we use jQuery show/hide methods.

This does not happen on IE nor on Firefox.

We notice the parts that become black are linear gradients we define in defs element.
