    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?!?

      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

                                    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?

                                      did you try to use the debug mode for track errors and see variables instances ?
                                      Is your two differents projects has same files contents (or the second project is just a test case maybe ?). If this two projects are new, then use a tool for compare files contents to show differences appears.
                                      then... you could also try to use valgrind tool from qtcreator.

                                          Hi guys

                                          I have boiled down the error to a line which when commented the filedialog works but I don't see any reason how that line is effecting the filedialog. I will need that line in my project so if someone can tell me how it is affecting the filedialog, It will be very helpful.

                                          Thanks

                                           ui->sideLayout->addWidget(wid1,Qt::AlignBottom);
                                          

                                          This line adds a widget to the sidelayout which is a vertical layout added in the mainwindow.ui file through the designer.

                                          Note: There are other layouts along with the side layout but they are not influencing
