IcedTea-plugin doesnt work completely

[helpdesk]

What I have:
Ubuntu 14 ()
Firefox 40.1
OpenJDK Runtime Environment (IcedTea 2.5.6) (7u79-2.5.6-0ubuntu1.14.04.1)
OpenJDK Server VM (build 24.79-b02, mixed mode)

I want to open a page that contains a real-time graph that loads through 
Java.
The page loads on a Windows machine perfectly fine running the latest 
Java. I want to open it on Linux.
On Linux, the page loads as it should. The page loads the background and 
the frame and grid work of the linear graph, but the linear data is not 
there. It doesn't load at all. However, when I open a new tab or 
enter/exit full screen, the linear data shows up

I have uninstalled Firefox, OpenJDK, and IcedTea-plugin; but after the 
reinstall, the same thing happens.
If you need any additional information, please let me know.
