On a few workstations in our department the Workbench didn't start (@cheray, @sattler). It's somehow related to QtOpenGL 5.6. "Luckily", @mpkh did have the same issue some weeks ago and he found a solution. In our mitk::BaseApplication we need to ensure the creation of an OpenGL context:

Thank you very much, @mpkh!
Not yet, but we will integrate it very soon. @gaehlert is currently testing if your fix resoves another issue on OS X in combination with QWebEngine as well.
Unfortunately, this does not resolve the rendering issues due to QWebEngine on Mac OS X.
Reverted the fix for now as the issue arose on even more PCs. However, the Workbench got stuck when loading QtWebEngine instead of QtOpenGL. So we may have a combination of issues here.
@kislinsk this fix works pretty fine for us, let me know if you will find some maybe better way to resolve it. or at least please share environment/video/steps to reproduce so we will know that there is something beyond my fix.
I just set up a complete new superbuild (mbi-mitk and mitk) and I have the same issues here. No build error, it starts to load the libraries but the workbench won't open.
As I reverted the fix today, can you please check what version is actually working, if any?
Just for documentation: mitk rMITK3d2ff8ee (6th July) and mbi rMBI0694951b1006 (4th July) are working.
I'll set up a new superbuild with the current master and let you know if it is working.
Current master (rMITK8c57782b and rMBI9756551ed5) is working for me. Workbench is starting.
After T19874: Make QtWebEngine an optional dependency I can reproduce the issue described here in T19851. When I switch on MITK_USE_QT_WEBENGINE, the Workbench doesn't start. It's happening somewhere in the Nvidia graphics driver. We should examine QWindowsOpenGLTester::testDesktopGL() for any hints. Here's the call stack:

Line 365 in QWindowsOpenGLTester::testDesktopGL() is a call to MakeCurrent().
From http://doc.qt.io/qt-5/qopenglcontext.html:
QOpenGLContext can be moved to a different thread with moveToThread(). Do not call makeCurrent() from a different thread than the one to which the QOpenGLContext object belongs. A context can only be current in one thread and against one surface at a time, and a thread only has one context current at a time.
Maybe this is a first hint.
I could reproduce that error at home yesterday and updating to 5.6.1 did not fix it for me
