Hey, thanks for the report. This looks like a known bug. We’re tracking it here: Cursor freezes on final “Review Changes” step in Agent Mode
We need to confirm details and collect diagnostics:
- Does the pattern match: it freezes if the Agent finishes while the Cursor window is not focused
- Request ID of the frozen chat: chat menu (top-right) > Copy Request ID
- Console screenshot: Help > Toggle Developer Tools > Console at the moment of the freeze
- MCP: Settings > search “MCP” - which servers are enabled. Try disabling all MCPs temporarily and restart
- Extensions: launch with
cursor --disable-extensionsand check - Process Explorer:
CTRL+Shift+P> Developer: Open Process Explorer - which process is spiking - Update to the latest version and check if the bug still reproduces
As a temporary workaround, try keeping the Cursor window focused when the Agent finishes a step. Let me know if this helps and please share the data above.
