Plotting with scilab-5.4.1 (from the science overlay) is not working on my ~amd64 system.

Nothing is shown in the graphic window that opens when the plot function is called, for instance, by entering the following expression in the console window:

  plot( 1:10, sin(x))

The correct commands typed into the console window are:

-->x = 1:10;
 
-->y = sin(x);
 
-->plot(x,y);

I have found the following FAQ, explaining what the problem may be.

I do not see any Java exception on the terminal where scilab has been launched.

But I see the following message:

libEGL warning: failed to create a pipe screen for i965

The discussion linked below in the jogl forum suggests it is a problem with the version of jogl:

Then I have found the bug https://bugs.gentoo.org/show_bug.cgi?id=488402 which may be related.
