Well it's been a while for V4 and I (we had to break up, the relationship was getting WEIRD).  But I have noticed random issues with V4's injection system where the standard morphs do not operate right.  Consistently, I mean.  Usually it's okay, sometimes its weird.

Also with community morphs, unless they are EXP for V4, there can be conflicts if using different morphs from different 3rd party packages.

Remember if you're using clothes (though Lali bits sounds like a not really clothes type thing) that you'll need to magnetize the clothes or you'll get pokethrough because of all the deformers embedded in V4 are adjusting the figure.

Flickering does sound like a graphics card/driver/something going bad issue.

Sorry couldn't be more helpful!
