Hi Stefano,

I don't know exactly. How can I check this and / or switch the engine?
When opening konqueror and access e.g. google.com then a new process is listed
with QtWebEngineProcess - so I assume this is the QtWebEngine.
I tried to search for kwebkit in aptitude - nothing found...
Maybe it is hidden in a different named package?

Best regards,

Erik
