I don't use it much, but I like to double-check that the PDFs I create view OK under Acrobat Reader (as well as Preview).
The other day, I used it on my MBP 15 (Apple Silicon) under Monterey. File was OK so just minimised and forgot it.
The next day, the machine felt very slightly warm, and I decided to check Activity Monitor. Acrobat Reader was using around 38% CPU - continuously. Even if I was doing nothing at all except watching the screen. Even if minimised. And I remembered it had done something like that some months ago. I'd just closed it and temporarily forgotten. Yes, I did check for updates (it was up to date then and now - 2022.002.20212).
Obviously it is easy to quit it. And it isn't, for me, a critical application. But it is pretty bad behaviour - and I'm glad I was on mains not battery.
