Looking at task manager, I found three instances of "Qt QtWebEngineProcess (32 bit)" running, each using roughly 16% of my CPU (i5 9600k six-core at 3.7GHz CPU).

When I access the process properties via the context menu, these processes show this location "C:\Program Files (x86)\Calibre2\app\bin". The processes remain running even when I close Calibre.

Has anybody else got a similar experience? Does anyone know why this is happening? If this is some kind of library optimisation process which will make the software run better in future, I will go along. Otherwise, I will surely downgrade - I want my PC to be silent when idle.
Nothing here (returns to 0CPU after a brief 'poll cycle'). Task manager says power usage 'very low' during Calibre idle (me not using it)
