Missing window updates and crash on Windows 10

I was testing Qt Creator from the Qt 5.8.0 beta package, Qt for Android. After a while of testing, right after having started a virtual machine, running an example on this, and then closing down the virtual machine, Creator starting acting weird. I don't know if it was related to this, but that is the last thing I did.

First it stopped getting window updates in the Qt Quick part of the window (see screenshot). Clicking menu items, for instance, still worked, but the application contents no longer filled the entire window (which was maximized).

When resizing the window, this disappeared, but then the application suddenly crashed:
