Obviously this is not something that impact everybody, but it is a real issue. I have the windows flashing on my screen sometimes multiple times per minute; very annoying.
I don't have the capability of fixing this, but is there someone who knows a workaround or fix?

Description
On Windows, a black console/terminal window briefly appears and disappears at regular intervals. This happens even when no prompt is sent — the app is idle.
Each flash corresponds to a subprocess invocation (git polling, file watching, LSP communication, etc.) that spawns a console window because the CREATE_NO_WINDOW flag is not set.
Expected behavior
Subprocesses should run silently without creating visible console windows. On Windows, this requires passing CREATE_NO_WINDOW (0x08000000) in ProcAttr.SysProcAttr when calling os/exec.Cmd.Start()
