Hi everyone!
On Thursday, **March 19,** at **03:00 PM UTC** , join us for a [live session](https://info.jetbrains.com/marketplace-livestream-march19-2026.html?utm_source=forum&utm_medium=post&utm_campaign=streammarch26) with Yuriy Artamonov, Product Manager for the IntelliJ Platform at JetBrains, hosted by Patrick Scheibe, IntelliJ Platform Developer Advocate.
In this livestream, we’ll explore **common causes of UI freezes in JetBrains IDE plugins** and how to prevent them.
During the session, you’ll learn:
- Why APIs like `ReadAction.compute` and `runReadAction` can block write actions and freeze the UI even when your code doesn’t run on the event dispatch thread
- Which patterns to avoid when working with read actions and background tasks
- How to write cancellable, freeze-safe plugin code that keeps JetBrains IDEs fast and responsive
At the end of the session, stick around for a live Q&A with our experts!

That was a really fun stream, thanks to everyone who joined. @yuriy.artamonov promised that we would share his `SKILL.md` file for analyzing thread dumps with regard to UI freezes.
