      Most developer have to debug  from  arbitrary logs like this case for me.

      QtCreator's Find in a large file(1MB+) cause UI to hang or not respond if there is mismatch.

      Then I can't input anything for 5 seconds or any more.

      At that time, cpu usage is high then machine fan sound get loud.

      There seems to be some performance Issue  compared to other tools like Sublime Text or Vscode or Android studio.

      Anyone can represent easy this problem with a large text file.
