Happens on my SuSE 12.0 box too when I start a Qt5 application X11/
remotely. Starting the same application locally works.

See https://bugreports.qt-project.org/browse/QTBUG-28000

When running Qt 5 applications over NX it results in a black screen for 
half of my applications, as soon as the application window gets 
activated. For the other half this effect doesn't happen but I can see a 
lousy graphics performance ( falling curtains ) - what is no surprise as 
the X11 paint engine has been removed from Qt 5.

Too sad that without the X11 paint engine all hardware accelerated 
graphics are gone too.
