Description Andrey Cherepanov 2014-12-29 18:28:56 MSK 
Scilab 5.X is doing an advanced use of JOGL (the Java Binding for the OpenGL). For performance reasons, we are using the Java2D OpenGL Pipeline. From a more technical aspect, it is using the internal buffer of the graphic cards called pbuffer.

...

Workaround
----------

From Scilab, execute the function:

  system_setproperty("jogl.gljpanel.nohw","");

Or launch Scilab wih hardware acceleration deactivated:

  LIBGL_ALWAYS_SOFTWARE=1 bin/scilab-adv-cli

На radeon срабатывает только

  LIBGL_ALWAYS_SOFTWARE=1 scilab

Вероятно, стоит изобразить обвязку вроде opengl-game-wrapper.sh из федориного opengl-games-utils: http://fedoraproject.org/wiki/SIGs/Games/Packaging
