Looking Glass support

I’m having trouble with the Looking Glass plugin with a Portrait display. It seems to work as it should with the Looking Glass test images, but not when attempting to render from Paraview. Is this the best place to look for support?

The essential issue is that nothing shows up on the display besides the extended desktop image. There appears to be a black square on the display that shows up when asking Paraview to render; perhaps it’s putting the image in the wrong place?

No errors in the Output.
