QWebEngine view renders solid black when app launched via Remote Desktop and Colors lower than 32-bit

To reproduce:

Using Window's Remote Desktop, choose Show Options, then with Display > Colors, set Colors to anything other than True Color (32 bit).

Now, using Remote Desktop, connect to a machine with Qt installed. Use Qt Creator to run the Demo Browser example project.

Result:

The browser's main window will be pure black. You can still 'interact' with the content (i.e. your mouse cursor will change as you move across different parts of the page, and presumably you can click links, too) but you can't see what you're interacting with.
