title: How to switch off disassembler in Qt Debug?
body: <p>when I try to set a breakpoint and debug I see the disassemler view. I tried to google the way to switch it off but these advices couldn't help. <strong>I have a debug regime and no tick near "Debug -> Operate by Instruction"</strong> </p>

  <p>so, <strong>I couldn't find the way to hide the disassembler screen</strong> </p>

  <p><strong>I have only ASCII symbols in my 'project' and 'build' directory paths</strong>.</p>
  
  <p>Tools->Debugger->Set breakpoint using full absolute path <strong>is switched on</strong>.
  <strong>Source path to project is added to Source Paths Mapping.</strong></p>
  
  <p>How to fix it?...
  I have QtCreator v. 4.5.0 (based on Qt v. 5.9.2), OS is Fedora 27.</p>
