When perf exits with some error it shows the error message with ui__error() or ui__warning() and then calls ui__exit() during exit_browser(). On TUI, it then shows a window titled "Fatal Error" to inform user a last message which might be related with this condition. However it sometimes contains no message and just annoyes users. The usual case for this is running perf top as normal user. (And /proc/sys/kernel/perf_event_paranoid being 1).
