I see it but no idea about a root cause.

I think it must be on the qtwebengine side of things; the same
occurs with konqueror.

If I force qt5 ("qutebrowser --qt-wrapper PyQt5" and make sure
py3-qt5/py3-qtwebengine are installed; config/runtime dir may need
cleaning if switching between them) then cpu use is a bit high
but not nearly as bad as with qt6webengine.
