    Description

      FramebufferObject with multisampling or float texture formats (GL_RGBA32F_EXT) does not seem to work (at least in ANGLE version of Qt).

      I checked it at the textureinsgnode example.

      format.setSamples(8);
      does not eliminate aliasing artifacts.

      format.setInternalTextureFormat(GL_RGBA32F_EXT);
      causes to "QOpenGLFramebufferObject: Framebuffer incomplete attachment" error.
