Fix it by explaining what can be happening and giving the number of processed and lost events. Also holler if unknown events were found, that can be due to processing a perf.data file collected using a newer tool where newer events got added on reporting using an older perf tool, that or a bug, so ask for a report to be made. Works on both --tui and --stdio.
