[Interest] Still getting crashes inside of Intel OpenGL drivers even after setting QT_OPENGL=software

Hello,

Top #1 crash of our app under Windows x64 is caused by Intel OpenGL 
drivers (for example: ig9icd64.dll).

We've tried setting environment variable:

qputenv("QT_OPENGL","software");

But we're still getting these crashes.

Why?

Unfortunately, the call stack can't say much...

0000000000000000()    Unknown
[Frames may be missing, no binary loaded for ig9icd64.dll]
ig9icd64.dll!00007ff9cc7c8dfb()    Unknown

We use Qt 5.10 + QML with QtQuick Controls 2.
