Livestream: UI Freezes in JetBrains IDE Plugins and How to Avoid Them | The JetBrains Platform Blog Join Yuriy Artamonov, an IntelliJ Platform expert, for a livestream on preventing UI freezes in JetBrains IDE plugins.

If you build plugins for @jetbrains.com IDEs, UI freezes are among the fastest ways to ruin the UX.

My colleague Yuriy will host a livestream on why they happen, how plugin code can accidentally block the UI thread, and how to avoid it.

Ok, the final call — which feed reader app is the best?

We run a survey among devs extending @JetBrains IDEs — heroes not working for us 🫡
We got an interesting insight into what's good and what's bad — a great road sign for us, and an interesting read for you! 📊

Check the @halirutan's article below. Cheers!

You can call me skipping intern 🫣

That’s not software, but it’s still good kind of development. I found my thing! — a jump rope — only earlier this year.

I’m not good at it yet, no tricks, but after twenty-something years in tech, I know it’s all about consistency.

Keep it up, whatever your drill is! 🙌

Gosh! After all, everything works stable, I believe. I’ve been using ThinkPads in the past — pure gold (also in terms of weight lol)

Is it really THAT bad??

The IT take on extreme sports? Start updating your OS a few minutes before the meeting. 😅

A nice explanation of the Stable Diffusion!

In only two minutes, Patrick can make you familiar with the concept of the "squint your eyes to see PyCharm in the mountains" thing. 🔥😑

Damn! I passed that again to YT folks. I'm sorry it happens to you :(

@youtrack.cloud, the best bug tracker ever 🐛

I fixed my desk setup — ergonomic again ✅

Now it’s time to start streaming. You’ll see plugin development, hacking, and fixing things, live and in public. 🎦

Want in? Tell me, and I’ll ping you when I’m online.

Do you know about `idea -e file.txt` Light Mode?

Haha, nice finding, Seb! 🥷

Easy to miss, but it’s a big one:

GitHub Dependabot can finally update the Gradle Wrapper 🔥

Do you rely on automated PRs in your projects?

Fair! 😇

That feature comes from another team that works on the IDE and IntelliJ Platform. That doesn't put Rider folks' efforts on hold!

TBF, I didn't try Fleet, so I can't tell 🫢

I've been told no one will notice that — prove them wrong 🫣

The upcoming 2026.1 release of JetBrains IDEs rolls out a smooth caret in the code editor to please your eyes! 💅

Hot or not??

P.S. Already available in 2026.1 EAP!
