Unusually high CPU usage with extreme lag

Going to Help > Diagnostic Tools > Activity Monitor, I get very high CPU usage:

%CPU  Subsystem
 
167.7  <Process total CPU usage>
33.7  Plugin CSS: psi.css.impl (in com.intellij)
24.5  progress (in com.intellij.openapi)
 9.2  <unidentified: JobScheduler FJ pool>
 8.4  Plugin CSS: webSymbols.css (in com.intellij)
 8.4  Plugin CSS: psi.css.impl.stubs (in com.intellij)
 6.8  <Garbage collection>
 5.3  reference (in com.intellij)

This results in heavy mouse lag. It's constant as well, does not slow down or stop over time.

Any ideas? Many thanks 🙏

Same issue for me when editing a file. Am running version 2024.1 with Git version control.

Hi,

Such cases should be investigated separately as the root cause can be different in each case.

Please submit a separate request via PhpStorm | Help | Contact Support or on YouTrack, and share details about your projects along with the logs from Help | Collect Logs and Diagnostic Data.
