    • Environment:
      Windows 10 amd64 Pro. Microsoft Visual Studio 2015 up 3

      CPU: Intel Core i7 7700K or AMD A4

      Video: Intel HD Graphics 630 or Radeon 8500M/8330

      Description

      Modify the standard sample from widgets/dialogs/classwizard so, for example, the first page contains an instance of QOpenGLWidget. Then all GUI child items and the window itself goes weird:the intro page will contain black rectangle in the title; the second page will be rendered incorrectly; seems that all items shifted up/down but their image is shown at the different position. See attached screenshots.

       

          All three available OpenGL-backends are affected: the issue is reproducible with QT_OPENGL=angle, QT_OPENGL=desktop and QT_OPENGL=software as well. Except when angle-backend is used there is only black rectangle in the title.

       

          Diff-file for the sample and the complete sample are attached.

       

          Reproduced on two machines: CPU Core i7 with Inte Graphics HD 630 and CPU AMD A4 with Radeon 8500M/8330 (notebook HP G255).
