Graphics Rendering and Missing Legend Labels

I typically use Software OpenGL because the Hardware OpenGL tends to crash my computer for heavy plots. I typically don't have problems with figures using Software other than the lower image quality. When I need nice images, I switch to Hardware. I have one very simple plot of three lines, when I plot them with Hardware OpenGL, two of the legend entries are missing. I need to use Hardware because the images are unacceptably low quality with Software. Does anyone know how to resolve this?

I am running MATLAB 2015a

Software OpenGL info:

                          Version: '1.1.0'
                           Vendor: 'Microsoft Corporation'
                         Renderer: 'GDI Generic'
                   MaxTextureSize: 1024
                           Visual: 'Visual 0x68, (RGB 24 bits (8 8 8), Z d...'
                         Software: 'true'
        SupportsGraphicsSmoothing: 0
    SupportsDepthPeelTransparency: 0
       SupportsAlignVertexCenters: 0
                       Extensions: {3x1 cell}
               MaxFrameBufferSize: 0

Hardware OpenGL info:

                          Version: '3.3.0'
                           Vendor: 'NVIDIA Corporation'
                         Renderer: 'Quadro NVS 290/PCIe/SSE2'
                   MaxTextureSize: 8192
                           Visual: 'Visual 0x07, (RGBA 32 bits (8 8 8 8), ...'
                         Software: 'false'
        SupportsGraphicsSmoothing: 1
    SupportsDepthPeelTransparency: 1
       SupportsAlignVertexCenters: 1
                       Extensions: {238x1 cell}
               MaxFrameBufferSize: 8192

The graphics card drivers are up to date. Thanks!
