The two attached graphs are the same view from the same analysis. The one on the left is displayed in Firefox 49. The one on the right is displayed in Chrome 53. This is the first time I have ever seen the problem exhibited in Firefox. Every graph I create in OBIEE 11.1.1.7 now displays in Firefox with a blue-gray background as shown, while the same graphs displayed in IE and Chrome are just fine. There is no background color on the graph, either for the plot area or the canvas.
Exact OBIEE version is 11.1.1.7.151020, so its about a year old.
Thoughts?
