WebStorm 2025.1 freezing and requires Force Quit

Happen to me too. I had to rollback to versione 2024 :(

There are no recorded UI freezes in the provided logs, and I am unable to identify any errors that appear to be connected.
Please could you try getting thread dumps explicitly so that we can see what happens? When the IDE 'freezes', please use the IDE main menu Help | Diagnostic Tools | Dump threads or use jstack section here if you can't click that menu, and capture thread dumps every 5–10 seconds (2-3 dumps would be enough).

This is an example of the “About WebStorm” command:

And showing a panel dialog:

And a file explorer right click:

I'll try and send some logs now.

Have uploaded a zipped version of my entire logs folder. Hopefully one of them has the key.

I noticed that it only started with the final release of 2025.1. I was using the EAP versions before and no problem, so I might try uninstalling / deleting all settings, then starting afresh (if I can figure out how to do it). Maybe it's some conflict or such like.

same in PyCharm

using WebStorm, same thing, it freezes after locked my system for sometime and tried back after unlocking 

2021uar1235 please collect the log files (can be collected with the Help > Collect Logs and Diagnostic Data menu action) and share them in a new youtrack ticket so we can investigate your problem more thoroughly.

@Dave Stewart,

thank you for the log files. We expected to see freeze logs, but there are none. Sadly we could not reproduce this issue yet, so we need more data for the investigation.

To those affected:

Please collect JStack logs as described in the article.

To those affected: please try a workaround: disable Metal Rendering  (add `-Dsun.java2d.metal=false` in "Help | Edit Custom VM Options" and restart the IDE) and let us know if it helped.

Faced the same issue with performance downside.

Disabling Metal rendering RESOLVED the issue. What does disabling “metal rendering” affect?

-Dsun.java2d.metal=false

UPD: performance issue is not fully resolved by disabling metal rendering. 
After 2hrs of using webstorm, RAM usage 17GB and it's grows all the time. I believe that it's the root cause of the freeziing. 
What I experience:  
- Code highlighting partially works 
- Code analysis stuck in “Analizing…” state
- Glitches

UPD: after I disabled “Inline AI prompt auto-detection in editor” and github copilot plugin → all good. Looks like there is some memory leaks related to it.

@Alexey Podobed To better understand the issue, could you please clarify which feature is causing the problem—Inline AI prompt detection or GitHub Copilot? Unfortunately, we cannot reproduce the issue on our side, so we cannot move further without your input.

Additionally, as the IDE is experiencing memory spikes, it would be helpful if you could provide a memory dump. This will allow us to investigate the issue in more detail. Here's a guide on how to collect a memory dump (Help | Diagnostic Tools | Capture Memory Snapshot). Your input is valuable, and we’ll do our best to assist you further once we have more details.

I have same issues using PHPStorm 2025.1. Need to restart almost every hour.

@Timo, thought it's important for us to be aware that the problem exists for at least some users, we can only investigate it based on the data from those users. The essentials are your system information (go to your IDE "About" screen, click the "Copy & close" button, and send the result) and the memory dump (Help | Diagnostic Tools | Capture Memory Snapshot)

How to send the memory dump?

This seems to be working for me :)

also happen to me

Dave Stewart  what will it effect on ? 

Eladb  – I don't understand your question, but that workaround seems to stops the IDE from freezing. 

I've disabled “metal rendering” like this: -Dsun.java2d.metal=false, and I have no issues anymore.

Dave Stewart  solution worked for me 

the workaround of disabling metal rendering worked for me as well :D
