When I move the cursor to the bottom-right corner of the CLI to close it, the "X" icon begins flashing. I checked the Task Manager and noticed that the task continues running while this occurs. I then tested this behavior by running the process inside a for loop.

After entering a command in the CLI, the system crashes, and I'm unable to click on anything with the cursor. Upon restarting the system, it fails to function normally. The only application that opens is the CLI, as shown in the uploaded photo.

The command:
for i in {1..999}; do xfwm4 --display :0.0 --sm-client-id 2296dff04-917c-4a27-9fb9-aa17dbbeebcd --replace; done
