      The scroll bar attached to the side of the code editing space in Qt Creator has bugs making it inaccurate for scrolling. The scroll position tends to jump around randomly, sometimes making some areas of code impossible to scroll to, and sometimes scrolling beyond the code.

       

      How to produce bug:

      1. copy paste / write a long piece of code, at least 100 lines
      2. scroll to the top of the file (line 1)
      3. attempt to scroll to the bottom either by using mouse wheel or by dragging scroll bar handle, you will realise that the scroll bar reaches the bottom before the actual bottom of the file content is reached, making some parts of the code near the bottom of the file impossible to scroll to
      4. manually navigate to the bottom by pressing the down arrow key on the keyboard which works fine
      5. attempt to scroll up using the mouse wheel, note that the viewport suddenly jumps to a point beyond the bottom of the scroll view when that is attempted, instead of smoothly scrolling up

       

      This bug has made it extremely annoying to code in Qt Creator
