Workaround sent to 5.6.1: https://codereview.qt-project.org/159688
Unfortunately, this issue now has become third priority... in order to debug
it, I need first to...
* debug why Qt applications forget their device pixel ratio status when the
screen is reconnected (reported as QTBUG-53500)
but to do that, I first need to
* fix Qt Creator to stop storming the X11 server with windows saying that
something crashed (I don't think it was the application being debugged, so it
must have been gdb)
but in order to debug Qt Creator, I need to fix the HiDPI situation so I can
read the text in Qt Creator. So I'm in a deadlock...
