描述

Problem Description

Flow Launcher, it appears to be triggering hundreds of events in rapid succession. This can overwhelm other applications that listen for these events, causing them to crash or become unresponsive.

Example of what Flow Launcher sends and I wonder what the reason for this is

研究方向
Investigate the event system in Flow Launcher, focusing on the settings page and search functionality. Look for loops or repeated event dispatches. Review the attached video and linked issue #375 for context. Check if there's a debouncing mechanism missing.
