all not DemoParticleFromFile are bad, only see a small part of effects, but in v0.7.2 is see all.
test by HTC G2 and Emulator v2.2.
I tried to reproduce this bug. It do appear on HTC G3 HVGA.
But on HuaWei u8800 WVGA, it looks OK.
Tomorrow I’ll dig this case more, on other HVGA devices besides HTC.
