    Hey

    I have some processing done and while it starts the qt windget will go "gray/frozen" in windows. But when processing is done, it never returns to normal...

    Any hints what should I look at ? It started out of nowhere recently...

    Regards
    Dariusz

      Check you're not using https://doc.qt.io/qt-5/qwidget.html#setDisabled, that could cause greying. Otherwise Maybe Windows shows disabled while busy processing and no UI servicing, not sure, but that should go away when UI loop reached again.

        @JonB I'm not using setDisabled and ui gets responsiveness back but is still grayed out. - weird as I can click on anything there...

        When It comes to grayed out.. I mean its "frozen" like windows app stuck

          hi
          try drag other window on top of your app and see if your app then re-draws.

          What platform is this ?

          Also if its still frozen after, meaning it does not react to clicks it means
          you still doing processing.

            @mrjj Hey

            I can control the app after processing is done but "freez" remain

            Dragging other widget over qt widget does not help

            The QOpenGLWidget appear to look "properly" while others are bugged.

            Win10 x64. Tried on 2 pcs. QT 5.13.1

              Hi,

              What kind of processing are you doing ?
              How are you doing it ?

                @SGaist Actually latelly I noticed that it happens without even doing the process. Just by creating new widget & QOpenGLWindow embeded inside as widget causes it. So no custom "processes" that I perform or calculations. Only creation of window... hmmm I moved to 13.1 lately, perhaps the .1 version has an issue o.o

                  Did you already tried with an earlier version of Qt ?
                  You might also want to check the graphic stack of the machines you are having trouble with. It could also come from the video card driver.

                    @SGaist Hey, nope did not try it yet. It happens on 2-3 different pcs. So I don't think its hardware limited, maybe OS? But dont think its drivers. Nvidia/intel gpus.
