Steps to reproduce:
- get the official QC 4.9 based on 5.12.2 built with MSVC2017
- starting it points out that OpenGL context cannot be created
- QmlProfiler and QuickDesigner are disabled
The beta packages for 4.9 had been based on 5.12.1 built with MSVC2015 which work fine on this machine.
Note: QC enforces angle to be used.. Setting the environment variable QT_OPENGL to software makes the above issue also disappear for the official 4.9 release based on 5.12.2
Not sure if related: I could not get any Qt5.12.2 opengl examples to run on this machine when using QT_OPENGL set to angle
