Opening a new terminal window in GNOME on Arch Linux leads to switching to the workspace with an existing terminal due to GNOME's default behavior.
The solution involves enabling the 'Launch new instance' GNOME Shell extension to ensure new terminal windows open in separate workspaces without changing focus.
Steps to resolve the issue on Arch Linux include verifying the extension, enabling it, checking its status, and testing the behavior.
By enabling the 'Launch new instance' extension, GNOME will open new terminal windows in the current workspace without switching to an existing one, enhancing multitasking capabilities.
