This actually sounds more like a problem with your video card driver
in Ubuntu. I've had different results with different video cards and
drivers using Unity specifically. So try to look into that.
In the meantime, you can try turning off OpenGL support by editing (or
creating) $HOME/.gnuradio/config.conf and adding:
[wxgui]
style=nongl
