Fullscreen -> small window in top left corner

I have systems that start applications that switch to fullscreen mode on their own. Most of the time this works as expected, sometime this results in a small window in top left corner.
This happens with different applications (reproduced with a VMware client and python with webview), different window managers (reproduced with openbox and fluxbox) and different hardware/driver. I think this is a regression from xorg-server 1.18.x to 1.19.0, had the first reports in December 2016.
With debugging output enabled in openbox I see a number of configuration events. In case of issue there are extra configuration events that switch the applications view to a small area in top left corner.
