26.609.4994.0
What subscription do you have?
Pro
What platform is your computer?
Microsoft Windows NT 10.0.19045.0 x64
What issue are you seeing?
Whenever session starts, "codex.exe --type=renderer ..." process keeps hogging CPU, as a result the UI becomes barely usable and unresponsive. Deleting .codex-global-state.json, all sessions and constantly growing logs_2.* is not helping.
What steps can reproduce the bug?
Just start a session
What is the expected behavior?
responsive UI
Additional information
Subjectively it started when this annoying "Invite a friend" item appeared on the Settings menu, because first the normal old menu appears first, then a second or two later appears this "Invite a friend" nonsense...
