You need to add a space between the paragraphs for it to work.

Like this.

I’ve been using it for years and never encountered any issues (besides the fact that they’ve removed comments from the download pages).

I’ve had this same situation happen to me before and my solution was to search -x instead of just x.

Windows 8.1 (~10 years) -> Xubuntu (a few months) -> Arch linux (present).

My guess is that sway checks sets the opacity when the window open, so when the first rule matches (app_id=.*) it skips all others, so maybe try putting the other 2 rules above the first one?

Sorry if my comment is incomprehensible, I’ve just woken up.
