Cursor IDE

Describe the Bug

I have a workspace in windows wsl. It works well when open the workspace with anysphere wsl externsion. After upgrade to Cursor3, it seems the wsl extension is not loaded correctly. It always prompts install wsl and reload, but after click the button, it reload the window, the wsl extension is still not loaded. It blocked the editor loading. I have to open the editor window first to load the workspace. The agent view does not work.

Hey, this is a known limitation. Agent Window Glass doesn’t support WSL connections yet. The extension installs, but Glass doesn’t activate it, so you end up in an infinite prompt loop.

Workaround: use Editor Window for WSL projects. You can open it from Agent Window via Open Editor Window, or start Cursor in classic mode:

cursor --classic

In Editor Window, WSL works as usual.

The team knows about the issue. There’s no ETA yet, but every report helps with prioritization.

+1 on this issue.

The new agents window promises to be a really nice “hub” for light interaction with a bunch of different workspaces from one place, whether they’re on my local machine, a server that I ssh into or wherever.

But without WSL working, it’s sadly not usable for this kind of workflow for myself and my team in it’s current state yet.
