   Thanks for updating the issue! It now includes a clear description, reproduction context, a screenshot, and system information. Everything looks good — the compliance flag has been removed.

   The mac version seems to have memory leaks as well. Starting a new session from within OpenCode with /new doesn't clear the memory use. Only way is to quite and then resume.

   I have a similar issue on Windows 10 Professional: the Bun process's CPU usage sometimes (during the build agent's execution) reaches 60+%. Memory usage is around 1 GB.

   Opencode TUI version: 1.2.20
   RAM: 16 GB
   CPU: Intel(R) Core(TM) i7-1065G7 CPU @ 1.30GHz

   P.S. In a previous version, I didn't notice high CPU usage, so the issue is quite fresh.

   Closing in favor of #20695 where we're collecting all memory-related problems. Please follow that issue for updates.
