Arduino IDE strange CPU usage

Development Tools IDE 1.x
1

Hi there!

I'm currently running the 1.8.7 version of the Arduino IDE. It works all right at first, but for some reason after a while the CPU fan speeds-up a little. And by checking at the task manager, I discovered that "javaw.exe" (the underlying process the IDE runs on in Windows) is stuck at 25% CPU usage (one of the four cores stays full-loaded during this) even when doing absolutely nothing.
It doesn't affect the functionality or performance of the software though, but it's still quite annoying for me.

So... what's going on? Does an update worth the hassle? Or the solution is somewhere else?

Thanks beforehand!

Why are you running the outdated Arduino IDE 1.8.7?

Have you checked to see if the problem still occurs with the modern 1.8.10?

And apparently you're right. Whatever bug it was, is fixed in this 1.8.10 version; so an update was the way to go.

Thank you anyways! :slight_smile:

You're welcome. I'm glad to hear the issue is resolved by the update.
