    Qt-based applications working with OpenGL were broken after driver update

    gshep_amd

      Hello!

       

      After the Intel Graphics 630 driver was updated Qt-based applications

      working with OpenGL were broken altogether.

       

          Tha last working version is 15.45.16.4627.

       

          Versions 15.45.18.4664 and 15.45.19.4678 are broken.

       

          To reproduce the bug one can use the attached sample (actually diff/patch for the oficial sample from Qt). The sample

      is from the official Qt's collection of examples but with a slight

      change: it contains QOpenGLWidget. Microsoft Visual Studio 2015

      with latest update is required to build the sample (Qt also must be

      built with the same version of the compiler; it can be downloaded

      from the oficial site qt.io).

       

          However if the backends software/angle are used the application

      works correctly and its GUI is not distorted.

       

          The bug is reproducibale with Qt version 5.7.0, 5.8.0 and the lastest

      5.9.0.

       

          Also if a dock-widget with OGL-context is detached from the main

      window or closed then the interface "partly" restores: I mean "partly"

      because it will be better but not correct as it should be.

       

           Screenshots attached:

      1. dockwidgets_QT5.9---no-openglwidget.png - main window with no opengl-widget child;

      2. dockwidgets_QT5.9---openglwidget.png - openglwidget shown. Notice that the font is not clear anymore; icons/toolbar shifted/cut; also right side of the widgets cut.

      3. dockwidgets_QT5.9---detached_openglwidget - openglwidget was detached from the main window (application was not restarted).
