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: > AppleSeed News Thanksgiving Break > Please note that our team will not be processing feedback during our Thanksgiving Break, November 18th through November 26th. Please continue to submit your feedback. We will process new feedback and respond to any inquiries when we return to the office on November 27th.

(In reply to Simon Fraser (smfr) from comment #5) > What apps are you seeing this with in Sonoma beta? 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. https://github.com/Jigsaw-Code/outline-client/issues/1786#issuecomment-1820868430 https://itunes.apple.com/us/app/outline-app/id1356178125 (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: https://forum.justgetflux.com/topic/8491/sonoma-14-2-beta-3-100-cpu/2
