Expose ViewID_OVR impostor in the fragment shader The OVR_multiview specification states that gl_ViewID_OVR is visible at each pipeline stage. Previously to this patch the ViewID_OVR impostor was declared only in the vertex shader and occurrences of gl_ViewID_OVR in the fragment shader were not being handled. The patch addresses the issue by declaring the ViewID_OVR variable as a vertex output in the vertex shader and as a fragment input in the fragment shader.
