Any chance the fix can be expedited into macOS? Sonoma beta is trashing battery in 1-2 hours because of this. To make matters worse:

1. Mail app. Though it’s tricky to reproduce: guess, it’s related to some specific HTML emails. But after a while it most definitely settles with 100% cpu usage — I keep quit the app after reading emails because of this. 2. The best candidate to illustrate this regression is Outline VPN client: just starting the app (without any vpn connection, just opening it is enough) immediately sends it to 99.7% cpu usage.

(Unfortunately, I don’t remember the dev discussion for some another app that traced the issue right to this specific regression — that’s how I ended on this page).

Found it: another app is f.lux. Here’s the discussion that brought me here:
