edit: I wasn't using Windows built-in Task Manager to measure Calibre CPU usage. Just now I tried it, and it went up to 60% for a while, during converting, so I guess what you see isn't unusual

It is possible that the problem you mentioned, the rendering engine has changed, which may bring about a sudden high CPU ratio, which is enough to make the computer blue screen crash
