when running under wayland (command line "XyGrib -platform wayland"), error is printed instead of displaying cross-tie cursor - QWaylandShmBuffer: mmap failed (Invalid argument).
This is caused by invalid pixmap inside cursor object, and at qwaylandcursor.cpp:251 img is invalid:
const QImage &img = cursor->pixmap().toImage();
Workaround is to use pixmap constructor for cursor instead of bitmap/mask constructor
