           Summary: WebGL color renderbuffers need to use 8 bit per
                    channel on desktop OpenGL
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebGL
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: bjacob at mozilla.com

WebGL color renderbuffers, like OpenGL ES, are 16 bits per pixel.

But desktop OpenGL implementations tend to not support these, and AFAIK only 8 bit-per-channel formats like GL_RGB8 and GL_RGBA8 are required to be supported in deskop OpenGL.

So renderbufferStorage needs to replace GL_RGB565 by GL_RGB8 and GL_RGBA4/GL_RGB5_A1 by GL_RGBA8 on these desktop systems, or else the framebuffer will never be complete.
