It is unclear at the moment why this happens. Seems like a hardware-specific issue with Skyrim dialog UI, and it is not caused by scripts or savebaked, so sharing a save does not show anything.
I built a test DLL with a probable workaround here https://mod.pub/enderal-se/38/comments?thread=1061 , test and see if this is still reoccurring.

As for why it happens, could that be because some of the mod's NPCs don't have greeting phrases? Other people mentioned similar problems happening in other mods because of that, for example this thread on Steam.
