ffx hogging CPU on macOS #121288
Description
The ffx process(es) has been hogging CPU on my M1 Max machine to the point where apps start freezing up and restarting is the only way out. I have no clue as to why these processes are running, as ffx is residing within the Fuchsia artefacts. Searching for related issues had no results. I've only experienced this on the master channel so far.
Unfortunately, since the issue kept halting my machine, I deleted the ffx binary before I could work out some more diagnostics and logs. I'm trying to reproduce, but I wanted to report this in the case of it being recently introduced and potentially be making its way onto stable at some point. Will update the issue with more findings.
Steps to Reproduce
- Install Flutter on macOS system, I'm on 13.2.1 (22D68)
- Somehow trigger loading/caching of fuchsia artefacts (should reside within
$FLUTTER_SDK/bin/cache/artifacts/fuchsia) - Start any flutter process
