The QQuickWidget we use, only support OpenGL and Software in Qt 6.2, and there is no other QRHIWidget available or planned. We will be trying with a QWindow approach for 6.3 or 6.4.
Another issue is that Chrome itself is still using OpenGL, on Windows using ANGLE, which Qt removed support for :/ Perhaps we can run QtWebEngine under ANGLE and the rest of Qt under D3D, but it is still at a research stage, and we are low on manpower. So it is definitely something we would like to get working, but there are many pieces not fitting together at the moment.
