Issue with MacOS

Thanks for this very nice Qt3d material.
I successfully run it under GNU/Linux but can't make it work with MacOS.
Here is my log :

            }

            void main() {
                lowp float alpha =
                    smoothstep(0.0, relativeSizeX, 0.5 - abs(0.5 - qt_TexCoord0.x)) *
                    smoothstep(0.0, relativeSizeY, 0.5 - abs(0.5 - qt_TexCoord0.y));

                highp float spreadMultiplier = linearstep(spread, 1.0 - spread, alpha);
                gl_FragColor = color * qt_Opacity * spreadMultiplier * spreadMultiplier;
            }

It seems the shader variant is not correct but I couldn't see from where it is loaded.
My Qt version is 5.7.1 and my OpenGL version is supposed to be 4.1 (from this kb https://support.apple.com/en-us/HT202823)

However glxinfo give me this feedback :

OpenGL vendor string: Intel Inc.
OpenGL renderer string: Intel(R) Iris(TM) Graphics 6100
OpenGL version string: 2.1 INTEL-10.22.25
OpenGL shading language version string: 1.20

Thanks for your help.

This is a bug of QtQuickControl2 material theme:
Its shadow shader is writing in OpenGL ES2 and your platform is detected as OpenGL ES3.x

It's quite interesting that the global context is set to GL(destktop), QtQuick still run in GLES context sometimes and in some part.

Change the theme to "Universal" (i.e the Windows one) may help.
