Hey, thanks for the report. This is a known issue. Computer use works during the initial environment setup, but on later agent runs the system doesn’t recognize the environment as testing-capable, so the Desktop tab stays empty.
Workaround: delete the environment.json file from the .cursor/ directory in your repo. After that, the dashboard config should get picked up, and computer use should work in new agents.
More details here: Cloud agents with environment.json can't use computerUse subagent (via the Task tool). Same issue, and this workaround is confirmed.
The team is aware. Let me know if the workaround helps.
