most likely the preview image is created from:
SfxObjectShell::CreatePreviewMetaFile_Impl()

called somehow by:
comphelper::EmbeddedObjectContainer::GetGraphicReplacementStream()

did you try if this setting has any effect?

Tools->Options...->LibreOffice Writer->Formatting Aids
"Math baseline alignment"

apparently this was a new feature in OOo 3.4, maybe there are some
obscure bugs with it still?  did OOo 3.3 perform better?
