[Bug]: altscreen not working on latest release

[r-vdp]

What did you expect to happen?

With the full layout, my terminal used to remain fully visible after exiting atuin, since atuin would draw on the altscreen and not on the main view.
On the latest release however, the terminal viewport always gets cleared.

I usually use alacritty with zellij and fish, but I also tested in foot, without zellij, running bash, and got the same behaviour.

What happened?

My terminal viewport gets cleared after every atuin history search.

I have the same issue.

I can confirm this is introduced in 18.4.0 and 18.3.0 does not have this behaviour. I have downgraded to 18.4.0 for me.

[ellie]

This is intended behaviour and is a default config change - we called it out in the release notes, but you can also read more here #2249

You can revert it with

style = "full"
inline_height = 0

in your config

Ah, I missed that the inline_height setting is the one that determines whether the alt screen gets used.

Sorry for the noise, it's working beautifully now!
