How does this look like on the screen (IMHO at leas some text and graphics should be missing)?
Does this happen with or without map rotation ?
Do you use map layer overlay ?
Also an unrelated question - can you check what Qt version is available in your Chroot and if QML and PySyide/PyQt are available ?
BTW, thanks to THP, there is now both PySide and Qt available for Android so modRana with the new Qt GUI should be also able to run natively on Android in the near future.
