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

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).

Hello!

First of all I am sorry for the late response. When you posted your

answer I was going on my vacation.

Our QA-team confirmed that the last version of drivers solves the issue.

Thanks a lot for your assistance!
