  I can confirm the existence of many 'about:' processes, also on macOS Catalina 10.15.7 using MailMate 5721. For me it's >100 of those processes, each of which using 80-100MB of memory.

  I'm aware of this issue. It's actually a side-effect of an intentional feature (a cache of recently displayed messages), but the memory usage is naturally unacceptable. I'll have to figure out a different approach.

  Besides the 'about:' processes mentioned above, I've also noticed multiple MTLCompilerService processes that are also related to MailMate. They're putting some real CPU load on my system and I usually need to close MailMate then, to be able to use my Mac normally again.

  In contrast to the 'about:' processes, they don't appear with every message read, but more seldomly — it seems related to HTML mails with images, but I'm not 100% sure.

  This seems to have gotten worse either in the beta releases or with macOS 12. Even with 64GB of memory, this eventually causes system stability issues after a day or two. MailMate had around 1800 processes using 17GB of memory, and surprisingly it was affecting Safari as well.

  Are there any workarounds for this?

  Which revision are you using now? Hold down the command key when clicking “Check Now” in the Software Update preferences window. As far as I know, this should be much better now.
