I'm getting a tmux message when switching back: "no previous window".

The session must be created by tmuxp, I'm using this one:

session_name: foo
windows:
- layout: main-vertical
  options:
    main-pane-width: 160
  panes:
  - blank
  - blank
  - blank

I start it from inside a tmux session (tmuxp load -y ./foo.yaml, -y or -d doesn't matter). I've noticed that I do get this message "no previous window", right when I start and enter the session with tmuxp load -y ./foo.yaml, prior to applying zoom, etc.

The message "no previous window" always shows up when switching to tmuxp created sessions. Not only it shows up, I've noticed there's now quite a delay for the layout to load up when running tmuxp load -y ./foo.yaml. It spends some seconds in a blank state before the layout loads.

With at least two sessions open, chose one and have multiple panes open on it. Zoom one of the panes (prefix + z) and then switch to another session. Now switch back to the session with the zoomed pane. On switching back the zoom state is lost.

I can't recreate it. My zoom is preserved.

I tried the yaml (on this machine, it's tmux 2.5 and the left pane is massive), and couldn't recreate the zoom glitch.

I believe it's happening to you, I just haven't been able to recreate it yet.

I should try it on tmux 2.6.

Missing zoom is secondary. it's lost because tmux is always emitting the error message "no previous window" at the bottom, which should reset the layout. There's also the issue regarding slower layout loading. For now I'm just pinned to tmuxp 1.3.2.

Is this the issue preventing you from using tmuxp at the latest version?

Just to make sure, you can still load the windows/panes via tmuxp. But the session zoom breaks the zoom state after tmuxp loads it, and it started happening after the hook added when fixing #312?

Got it. So if #364 is fixed, this should be fixed?

Most probably yes.

#364 is just a reopened duplicate of this one due to the stale bot.

I thought #364 description was pretty clear on that...
