I should point out that this affects the Adreno 200 in my ZTE Blade too. It doesn't bother me so I've not mentioned it.

I have a complete backup of my phone state and this app and its data so my phone is a perfectly safe test bed and it wouldn't matter in the slightest if any beta code trashed everything.
I also have this other minor issue:
