Crazy amount of "page faults"

I am author of RSS Guard application.

Recently, one user reported this.

RSS Guard uses QtWebEngine module to display webpages and it seems that WebEngine is responsible for crazy amount of "page faults" detected during app runtime. It goes to millions easily, exceeding any other app by huge margin, by magnitudes.

"Page faults" counter jumps by 10 000 or more everytime any WebEngine operation happens, like calling "QWebEngineView::setHtml" etc.

RSS Guard can also be used without WebEngine dlls and that variant of app is unaffected. Maybe this is not any bug or so, but it seems just weird as "page faults" are really hardly cause by any direct programming errors etc.

Can anybody shed some light on this?
