Webstorm 2019.1 high cpu load after long time idling Follow
After upgrading to Webstorm 2019.1 I have the problem that when I keep it open over the day (mostly idle in the background) in the afternoon the CPU will spike up incredibly, making the OS slow and letting the fan sound like a helicopter. I need to force quit it over the activity monitor, a normal quit is not possible.

Please try taking CPU snapshots when the issue occurs (https://intellij-support.jetbrains.com/hc/en-us/articles/207241235-Reporting-performance-problems) and provide them along with your log folder zipped (Help | Compress logs and show in Finder)
I seem to not be able to tick that option - it's greyed out...
Plugin is enabled though..
You need modifying vmoptions to enable CPU profuiling, please see (https://intellij-support.jetbrains.com/hc/en-us/articles/207241235-Reporting-performance-problems for instructions
I have the same problem. Can't take CPU snapshot because IDE doesn't respond, but get dump from

I had the same issue, switched back to 2018.3, waiting for a fix.
Having the same issue
Same Issue here. Still a problem in Version:
WebStorm 2019.2.3
Build #WS-192.6817.13, built on September 24, 2019
Runtime version: 1.8.0_171-b11 amd64
VM: Java HotSpot(TM) 64-Bit Server VM by Oracle Corporation
Windows 10 10.0
GC: ParNew, ConcurrentMarkSweep
Memory: 1967M
Cores: 8
Could not snapshot the problem, because as soon as I select the DropDown Menu like File, Edit, View,... CPU usage goes down. Was able to spot something with the Java VM Thread View:
After a few minutes this Thread starts :AWT-EventQueue-0 2019.2.3#WS-192.6817.13 WebStorm, eap:false, os:Windows 10 10.0, java-version:Oracle Corporation 1.8.0_171-b11 2019.2.3#WS-192.6817.13 WebStorm, eap:false, os:Windows 10 10.0, java-version:Oracle Corporation 1.8.0_171-b1
and causes high CPU usage.

you can turn sampling on to auto-enable profiler on application start (https://intellij-support.jetbrains.com/hc/en-us/articles/207241235-Reporting-performance-problems#capture_slow_startup_2019_1), start the IDE, wait till the indexing completes, reproduce the issue and then close the IDE. CPU snapshot file will be saved automatically after your close the IDE into your HOME/snapshots directory with the .snapshot extension.
Your log folder (Help | Compress Logs and Show in Explorer) would be also helpful
I uploaded the snapshot file to https://uploads.services.jetbrains.com/

Switching the Runtime Java Version to 11 solved the problem for me.

Can confirm the same issue happens on version 2019.3, OSX(10.15.6).
Not sure if webstorm is using build-in jre, but I tried to set Java_home to java8 / ava11, the problem appears on both java versions.
