Hello Humberto,

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,
