Thanks for your response Allan.

Looks like overriding the renderer with
QQuickWindow::setGraphicsApi(QSGRendererInterface::Software) *after*
calling QtWebEngineQuick::initialize() seems to activate software
rendering in Chromium. However, performance with Video (JITSI in my
use case) is subpar :-( Any plans to enable Hardware Acceleration in
Chromium with the "native" RHI backends (D3D11, metal)? Or is this
technically imbossible (due to Chromium limitations)?
