[Qt-creator] QtCreator 4.3b1 background thread running?

-noload Welcome is not required anymore, since the Welcome Page was reimplemented using widgets.
An alternative to avoid OpenGL issues on Windows is "set QT_OPENGL=software".
I cannot reproduce the issue on my Windows 10 setup.

Hi, you could try starting Qt Creator from a CMD window (universal solution #1 for opengl problems) to see if the CPU consumption subsides:
qtcreator -noload Welcome -noload QmlDesigner -noload QmlProfiler
