Updated today 03/16/2026 to the latest Windsurf plugin and cannot type in the IDE anymore while pluging is enabled.

Hello @latent kayak, have you tried restarting the editor? If it persists, send me a clip or something so I can look at it in more detail.

Not sure what kind of recording would be helpful here, what I can say is that downgrading to the 2.12.13 works both 2.12.14 and 2.12.15 show the same issue

Hello @latent kayak, one of our engineers suggested a quick test.

Could you try setting Completion Mode → Off in the Windsurf settings to see if the typing lag disappears?
You can find it in Settings → Tools → Windsurf → Completion Mode.

This will help us confirm whether the issue is related to autocomplete in the latest plugin version.

I am experiencing the same issue with IntelliJ IDEA Build #IU-253.32098.37 (built on March 17, 2026) when using the Windsurf plugin versions 2.12.14 and 2.12.15. For now, I had to downgrade to version 2.12.13, which works correctly.

@short pond just tried the newest 2.12.18, same issue, reverted back to 2.12.13

Seeing same behaviour here - makes code editing in any JetBrains product unusable.

@short pond if you don't mind, would you please share the update on this, was the issue identified?

Hey everyone! We're investigating an issue causing high memory usage in the Windsurf language server and would love your help gathering some diagnostic data.
Please follow these steps:
1. Download the language server binary

  • macOS: language_server
  • Linux x64: language_server_linux_x64
    (Links will be shared below / see attachment)

2. Find the path of your currently running language server
Open the Output panel (Cmd+Shift+U) and go to the Windsurf tab. You'll see a line starting with Starting language server with command: – copy that path.

3. Replace the binary

  • Close Windsurf
  • Move the existing language server binary to a different location (as a backup)
  • Place the downloaded binary in its original path

4. Run Windsurf and capture the profile
After restarting, search the Output for [PROFILE-DEBUG] and send us those lines.
Thank you so much for helping us track this down! 🙏

Hi @latent kayak, thanks for sending the log file. One more thing that would help a lot: could you please send the contents of the heap_snapshot file as well? The path to it should appear in your logs. If possible, please open that file and paste its contents here, or upload the file directly. That would be very helpful for the team to investigate this further.

latent kayak

there are many of them, which one?

Do many heap_snapshots appear? Try to download them and send me all of them

@short pond on the old plugin I'm now getting "Failed precondition: Your weekly usage quota has been exhausted. Please ensure Windsurf is up to date for the best experience, or visit windsurf.com to manage your plan. (error ID: a587a77263e549de8cec1f3842e601e5) (trace ID: 4bf5a034a3ba0acf6990c3955a47b07b)" we are on the Enterprise plan so I assume on the new plugin it would just add more money/credits but I cannot use the new plugin, this is very frustrating

never mind the new plugin also blocks me, you guys really want to lose all your loyal customers, looks like
