Description
Surface Example and Bars Example are both broken under both Gnome Wayland and KDE Wayland.
Qt 5.12 Beta 4. Under Gnome under Wayland, I can't get the Bars Example or Surface example to display anything - the application runs but does not display anything. This is when running the application with QT_QPA_PLATFORM=wayland. For the Bars example the output is:
13:33:27: Starting /home/myk/Qt/Examples/Qt-5.12.0/datavisualization/build-bars-Desktop_Qt_5_12_0_GCC_64bit-Debug/bars...

For the Surface Example, the output is much the same:

Bars example under KDE under wayland shows the window (no decorations) but no data visualisation, just controls on the right side. The application output is:
