Qt Creator in designer tab displays black frames.
At the same time in Konsole I have the following message several times (more than 30 times):
QQuickWidget cannot be used as a native child widget. Consider setting Qt::AA_DontCreateNativeWidgetSiblings
I tried to find the solution in Internet, but, unfortunately they don't work. How can it be fixed?
P.S.: Kubuntu 15.04, Qt 5.5.0, NVidia drivers 346.
