I think I've seen this kind of problem before, caused by buggy graphics drivers, but I'm not sure how to tell if that's the case here.
Do Kivy apps like this one have the same problem?

Yes - the Python 3 support on Android is still somewhat experimental and may need an extra step compared to Python 2 builds, but this is mainly because it hasn't seen nearly as much use as the Python 2 build. It does seem to work fine. I made an app called Pyonic interpreter partly to stress test it, but haven't had any problems related specifically to the Python 3 build for a while.
