[macklinu]

Description
When opening the built-in Zed terminal and then resizing the Zed application window, I notice a television crash. Please let me know if you need more info.

Example

• open zed
• press ctrl+`
• use fish shell (perhaps related since that's what i'm using)
• resize the zed window
• see crash

Expected behavior
No crash

Environment

• OS: Mac OS 26.1.0
• TV version: 0.14.1
• shell: fish
• terminal: Zed terminal
• Your configuration file (~/.config/television/config.toml)

#
# XDG dirs:
# ---------
# You may use XDG_CONFIG_HOME if set on your system.

# branches to choose from.

# by the corresponding commands.
# Example: say you want the following commands to trigger the following channels
# when pressing <CTRL-T>:
#          `git checkout`  should trigger the `git-branches` channel
#          `ls`            should trigger the `dirs` channel
#          `cat` and `cp`  should trigger the `files` channel
#
# You would add the following to your configuration file:
# ```
# [shell_integration.channel_triggers]
# "git-branches" = ["git checkout"]
# "dirs" = ["ls"]
# "files" = ["cat", "cp"]

Update: I can also reproduce this in ghostty with fish shell by resizing the ghostty application window

Hey, thanks for the report.

Is tv in a stabilized state when the crash occurs?

What I mean by that is are you able to open a channel, see the UI, and then observe a crash when resizing?

The bug report you sent seems to indicate that TV crashes before even starting its main loop, in the couple of milliseconds that separate the start of the application from the UI getting displayed, which is curious since it does not seem to have any link with resizing the window. 🤔

[macklinu]

Apologies for the delayed response but hoping a video of what I do to get this to crash will help in debugging.

I'm not able to reproduce on macos tahoe + ghostty + fish unfortunately.
