I've done further testing on a total of four machines using the performance feature of Google's devtools (inspector): 3 Windows 10 (one virtual) and one Linux. In none of the tests did the rendering time of any pages increase by disabling QtWebEngine's hardware acceleration. In fact, the rendering time actually decreased on three of the tests! That surprised me. Hardware ranged from my dog-tired i3 Dell laptop, to an 8 core i9 with 64Gb of Ram. All have what I would call very modest video hardware.
