Since the launch of workspaces on the new agent editor I’ve noticed that I haven’t been able to create a new workspace because it completely lags my computer, can only guess this is a memory leak of some sorts.
Steps to Reproduce
Literally just creating a new workspace with 2 or more folders.
This is a known issue with Glass (the Agents Window) and multi-root workspaces. When a workspace contains multiple folders, several Glass components scale with the number of roots, which can cause significant lag on lower-RAM machines like yours (16GB).
Our team is working on multi-root performance improvements for Glass. No ETA to share yet, but it’s actively tracked.
Workarounds for now:
Switch to the Editor layout temporarily: Cmd+Shift+P > search “Toggle Editor Layout.” Several users have reported that switching from Agents Window back to the Editor Window resolves the lag immediately.
Use single-folder workspaces instead of multi-root — open each folder in a separate Cursor window rather than combining them into one workspace.
Restart Cursor periodically (Cmd+Q then relaunch) if you notice lag building up over time.
If you’re able to capture a Process Explorer snapshot when the lag occurs (Cmd+Shift+P > Developer: Open Process Explorer), that would help us understand which process is consuming the most resources. Let me know if switching layouts helps or if you run into anything else.
