    I used QOpenglWidget in my qt software to draw some picture.
    But I found that in some windows 10 machine,when I used QopenglWidget,then the GUI's all widget cannot display。
    I have not do any modify of QOpenglWidget。
    Why have this problem?

      @luzhigang Most probably the reason is the graphics driver. Do you see any warnings/errors in the console if you start your app?

          @jsulm Thank you for your reply.
          Yesterday I also doubt whether was graphics driver's problem,So I checked whether have the new driver update,but it seems the driver is the latest version.
          It do not have any warnings/errors when I start my app.

            Hi and welcome to devnet,

            Did you check if there was any difference in the hardware between the machines where your application runs and the others ?
