Describe the bug

As the title says, when previewing PDF files in yazi (inside alacritty), the entire Hyprland session dies.

Testing with kitty, this does not happen.

Minimal reproducer

• Install Arch
• Use Hyprland Window Manager
• Install alacritty
• Install poppler to handle previewing of PDF files
• Start yazi with alacritty -e yazi

Anything else?

Tested both yazi and yazi-nightly-bin, both causes the same issue.

Checklist

• I tried the latest nightly build, and the issue is still reproducible
• I updated the debug information (yazi --debug) input box to the nightly that I tried
• I can reproduce it after disabling all custom configs/plugins (mv ~/.config/yazi ~/.config/yazi-backup)

Alacritty doesn't support any image protocol by itself, so Yazi uses ueberzugpp for it.

Please confirm if this is a bug in ueberzugpp, https://yazi-rs.github.io/docs/image-preview#debug-ueberzug

... * CRASH* ...

So yep, looks like a bug in ueberzugpp then. 👍

[sxyazi]

Thanks for confirming. In this case, I suggest reporting it to ueberzugpp for support since this isn't an issue with Yazi itself.

In the meantime, you can uninstall ueberzugpp so that Yazi won't use it, or use this trick to force Yazi to use Chafa as a temporary workaround:

XDG_SESSION_TYPE= WAYLAND_DISPLAY= DISPLAY= yazi

Closing as not Yazi, nothing can be done here
