Black screen Areas in designer (qtcreator)
I am trying out Qt on Ubuntu Linux 15.04 using Qt Creator 3.4.0 (opensource). When I switch (in the default QtQuick project) to the designer, certain areas are black (see screenshot): http://de.tinypic.com/r/kd0qwz/8
On the console output I get a lot of messages like this:
QQuickWidget cannot be used as a native child widget. Consider setting Qt::AA_DontCreateNativeWidgetSiblings
I find other posts on the internet about this, but no answers.
Well, it turns out the problem where the system wide qt5 libraries. I had to remove them, and everything worked. Unfortunately that also meant removing any qt5 application, like kde5.
I have the same problem. Created a bug ticket here:
