I also tried two more examples of qt5_gui module (qtbase/examples/gui),
the rasterwindow and analogclock. To include these examples in the
compilation mechanism of Genode I relied on the example
"qt5_openglwindow". Both examples compiled correctly, but do not run as
they should. I tried it on Qemu with pbxa9 using the foc kernel.
could you provide a Genode branch on github or a patch with the changes
you made, so I can easily reproduce the problem?

With the help of some printf in the example rasterwindow I determined
that the application fails in the renderNow() function, specifically
when call the following code:
QPaintDevice *device = m_backingStore->paintDevice();
Output to run the application with foc_pbxa9:

I hope this clarifies my problem.
In the patch are the printf I used in the application code.
Thank you,
