I can confirm this one, this happens even when the response is not large at all, the CPU usage spikes up to 100% for a few seconds

Same here, large json will cause memory leak, the latest version (25.10.1) will cause all cpu cores full loaded everytime it send a request and recover when request completed.
macOS 15.7.2

@JohnICB commented on GitHub (Dec 23, 2025):

It is also happening in v2025.11.2 using the self hosted version (macOS 26.2 (25C56))

Sometimes the UI crashes and it goes blank and unresponsive. The workaround is to close and reopen and it will work fine for a while.

and the app:// process seems to crash, but the rest still remain

Does not seem to be impacted by size of request or response.
