Hi, I’m just wondering if you’re also affected by https://youtrack.jetbrains.com/issue/IJPL-243919/Image-Animator-High-CPU-usage.
I verified this on different machines, OS, IDEs, IDE versions. For me, it’s easily reproducible. 2026.2 (eap and built from sources), 2026.1 and 2025.3.4 IDEs are affected.
Globally, open the plugin manager, select the Marketplace tab, select the AI Assistant plugin, wait until you see its first screenshot, then close the plugin manager.
Now, your IDE constantly uses 10~40% (it fluctuates a lot) of your CPU, and it never ends.
There seems to be a problem with the “Image Animator” when you display some specific images via the plugin manager (this is why I mention the AI Assistant plugin. The plugin itself is not faulty).
You can see this via Help > Diagnostic Tools. You will see two “Image Animator” threads that eat the CPU forever, even when idle. For now, I found no workaround, except restarting the IDE. It seems also to happen under different circumstances, but it’s seems 100% reproducible with the plugin manager.
If you’re affected, please up vote the issue. From my point of view, this is clearly a major issue.
On my laptop, the fans speed up just because of that, which is super annoying.
