Hi Elvis,
I've got a Win10 laptop (dell precision 5510), with an Optimus setup - both
intel and nvidia graphics.
With your test case, I'm able to see the volume running either with Intel
or nVidia, so it doesn't repro for me.
I've got Intel HD530 graphics, with driver version 21.20.16.4627
Sorry,
Aron
