2D View of TriSurf Problem

I have a 3D plot that I generated with trisurf (for a 2D CFD solution). In the isometric view, it looks great. However, if I look down the z axis (using view(2), or just rotating), most of the color disappears. I end up with oddly shaped blobs of color that don't correspond to my mesh, while everything else is white. This is particularly true for the large area of zero height surrounding the "pulse" I have.

However, when I save the figure as an image, the problem corrects itself.

I am looking at the time evolution of a solution, though, so I would like to see the accurate plot from the program, not saving it.

Any help is appreciated! Thanks.

Please check

get(gcf, 'Renderer')

If it does not say opengl, then try

 set(gcf, 'Renderer', 'opengl')

and if it does say opengl, then try

opengl software

If that does not work try

set(gcf, 'Renderer', 'zbuffer')
