[Interest] QWebEngineView + QSurfaceFormat == errors in console

[Andy]

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
OpenGL.

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

[79260:87779:0504/172025.710427:ERROR:gpu_command_buffer_stub.cc(590)]
Failed to create shared context for virtualization.

[79261:775:0504/172025.710803:ERROR:command_buffer_proxy_impl.cc(231)]
Failed to send GpuChannelMsg_CreateCommandBuffer.

[79261:775:0504/172025.710877:ERROR:context_provider_command_buffer.cc(262)]
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.
