How to Investigate UI Freezes

Summary

The presentation focuses on investigating UI freezes in IntelliJ Platform's integrated development environment (IDE), examining the architectural foundations of UI threading and concurrency. The speaker, a software developer specializing in threading models, discusses the Event Dispatch Thread (EDT), Swing framework interactions, and the platform's read-write log mechanism for managing shared mutable states like syntax trees and file system representations. The key takeaway is understanding how seemingly innocuous code submissions to the EDT can potentially freeze an IDE, highlighting the importance of careful thread management and event handling in complex software environments.
