Ubuntu 22.04下YAD托盘图标在GNOME终端/启动应用崩溃，VS Code终端正常

Ubuntu 22.04下YAD通知图标脚本在GNOME终端/启动应用中触发Gtk关键错误
我在Ubuntu 22.04（Jammy Jellyfish）系统上编写了一段创建YAD通知图标的Bash脚本，该脚本在Visual Studio Code内置终端中运行正常，但在GNOME终端执行./yad-debug.sh或设置为启动应用时，会触发Gtk关键错误。
脚本代码
#!/bin/bash # Stop on error (always a good practice) set -e # Create a FIFO file, used to manage the I/O redirection from the shell PIPE=$(mktemp -u --tmpdir ${0##*/}.XXXXXXXX) mkfifo $PIPE export PIPE # Attach a file descriptor to the file exec 3<> $PIPE # Add a handler to manage process shutdown function on_exit() { # Send command to YAD through pipe echo "quit" >&3 rm -f $PIPE } trap on_exit EXIT # Create the notification icon yad --notification \ --listen \ --image="/path/to/icon" <&3 & while true; do sleep 60 done
触发的错误信息
(yad:29692): Gtk-CRITICAL **: 15:21:14.013: gtk_widget_get_scale_factor: assertion 'GTK_IS_WIDGET (widget)' failed
尝试的解决动作
我尝试匹配Visual Studio Code的环境变量，但问题未解决，脚本已指定使用/bin/bash。以下是VS Code与GNOME终端的环境变量差异diff：
