It is hard to say what might have changed. If you didn’t change Qt and you didn’t change your application, then chances are that it was something in the system. Maybe the vsync driver change wasn’t applied? It’s all guesswork at this point :)
This part of Qt (how animations are driven on windows) has not been updated since 5.1.
The Qt download says “OpenGL” in the name if it is a proper OpenGL build. Otherwise, it is an ANGLE build (OpenGL ES 2.0 emulated over DirectX). You can also check this by looking at the dependencies of QtGui.dll. If it links with opengl.dll, it is an OpenGL build. If it links with libEGL, it is an ANGLE build.
