    Just a guess: What's the parent instance (this) that you pass to the QFileDialog::getOpenFileName(...) method?
    Is it an insvible window? (This should not be a problem but it seems that something influences the dialog box)
    And: Does the dialog show up in fullscreen? Does the dialog look normal when you try to resize it using the mouse?

      No. Its the mainwindow already holding several widgets. Yes, the dialog shows up in full screen and also I am unable to resize it from the bottom

        Hm, I think the reason for the display problem is the fact that the dialog is in fullsize mode (I'm not sure if this is really supported - on the other hand there's no reason why it should lead to a mixed up layout). And I have no idea why the dialog runs in fullscreen.
        Could you try once to pass NULL instead of this just to see if the dialog layout changes?

          I tried by passing NULL and also made sure the mainwindow is not maximized but still same problem persists

            Ok. so it is your project somehow?!?

            And this happens as shoow as it open the dialog?

            Does it only do it on ubuntu?
            (the same code)

            I tried the same code in the same system. It works on a new project but not on an existing one. I am unable to find a valid reason for this unusual behaviour

              ok. its really , really odd.

              Could you try with the
              QFileDialog::DontUseNativeDialog
              flag and see if its the ubuntu dialog that is strange?

                    Same thing happens even with flag?

                    Hmm. I really have no idea what can do this.

                    Also since it works normally in default app and
                    the static call is the same.

                    Have you tried some of the other dialogs ? like COlorDIalog?

                        Its like the getOpenFileName, just to get a color and not a filename.

                        http://doc.qt.io/qt-5/qcolordialog.html

                        I just wonder if that is funky too.

                                  That's really strange. Can your share a minimal runnable code example so that other users can try to reproduce the behaviour on their platforms?

                                      But you call the function on a menu click?
                                      not in mainwin constructor ?

                                      since it just in that project, im out of ideas. your Qt should be fine.

                                          No. Its the mainwindow already holding several widgets. Yes, the dialog shows up in full screen and also I am unable to resize it from the bottom

                                          Hi,'

                                          Yes, the dialog shows up in full screen and also I am unable to resize it from the bottom

                                          It sounds like the event loop is blocked. I don't see how that might be happening from your snippet, but perhaps you could post the rest of the code - the whole method and how it's called?

                                          Kind regards.
