    Description

      I'm running Canvas3D inside a QQuickWidget - I also have this patch applied:
      https://codereview.qt-project.org/#/c/163864/

      I was implementing the a lens-distortion effect in a Canvas3D - using this WebGL example as reference:
      http://www.decarpentier.nl/downloads/lensdistortion-webgl/lensdistortion-webgl.html

      It crashes somewhere inside ANGLE - it does seems to only a Winodws issue, on Linux ANGLE is not involved.

      I provide an example that should reproduce this crash.
