Ok I found the solution I was using:
> var output = execProcess("cmd.exe /c ipconfig")
Which caused the console to flash when app is compiled with --app:gui
when changed to:
> var output = execProcess("cmd.exe /c ipconfig" , options={poUsePath,
> poStdErrToStdOut, poEvalCommand, poDaemon})
It solved the issue.
Thank everyone!
