After upgrading to org 9.6, I find that refreshing the org buffer with org-ctrl-c-ctrl-c causes the entire buffer (including drawers and other folded items) to become visible.
I've tested this with a minimal config and the following org file: --8<---------------cut here---------------start------------->8--- #+title: A buffer * Test :LOGBOOK: - Note taken on [2022-12-09 Fri 11:50] \\ A note :END: --8<---------------cut here---------------end--------------->8--- What I expect to see after typing C-c C-c on the #+title keyword: --8<---------------cut here---------------start------------->8--- #+title: A buffer * Test... --8<---------------cut here---------------end--------------->8--- Instead, what I see is the entire buffer including the drawers. In a large buffer with many drawers, this causes problems because the drawers remain open even after cycling visibility locally or globally. Git bisect suggests that the problem first appeared with commit b8a0ddf52f4d5b5a3293affb45d1e8fd0426a7f0. Thanks, Matt
