[Interest] QWebEngineView + QSurfaceFormat == errors in console

I'm looking at using QWebEngineView to generate reports. When I display the
view my application is producing a lot of errors in the console related to

[79260:87779:0504/172025.710383:ERROR:gl_context_cgl.cc(136)] Error
creating context.

Failed to create shared context for virtualization.

Failed to send GpuChannelMsg_CreateCommandBuffer.

GpuChannelHost failed to create command buffer.

To reproduce, modify the webenginewidgets example called "minimal" and add
this in main() before everything else:

   QSurfaceFormat format;

   format.setVersion( 4, 1 );

   format.setProfile( QSurfaceFormat::CoreProfile );

   QSurfaceFormat::setDefaultFormat( format );

When I run it I get these errors:

[85081:53011:0504/174550.797117:ERROR:gl_context_cgl.cc(136)] Error
creating context.

[85081:53011:0504/174550.797870:ERROR:gl_context_cgl.cc(136)] Error
creating context.

[85081:53011:0504/174550.799549:ERROR:gl_context_cgl.cc(136)] Error
creating context.

[85081:53011:0504/174550.799997:ERROR:gl_context_cgl.cc(136)] Error
creating context.

GVA info: Successfully connected to the Intel plugin, offline Gen75

What am I missing?

Thank you for your time.
