    here is the mac system openfile dialog picture when I use the mac system App 'TextEdit':

    0_1553498881711_2.png

    the mac system openfile dialog picture when I use the mac system App 'TextEdit' is better, in my App, I don't write any change the mac resolution code at all, why my app look blurry and affect the system openfile dialog? and how to solve it?

      Hi @Princein,

      • which macOS version?
      • which screen resolution?
      • which Qt version?
      • how do you open the file dialog from your code?

      Regards

      Qt has to stay free or it will die.
