Mail Web Content memory leak

macOS 12.4 Monterey on Apple M1 iMac


Every so often (about once a day), my whole system slows down and I when I check on Activity Monitor, 'Mail Web Content' seems to have a memory leak as it's using 10 or 20GB or RAM.


If I Force Quit the process or Quit Mail and re-launch, it starts again from a low number but builds up over a minute or so.


Sometimes, force quitting a few times does the trick. Sometimes I just have to keep Mail off for a while and then launch it again later.


Anyone else has seen this and knows what could be causing it?

iMac Line (2012 and Later)
