@gioman I think the problem is the geometry displayed by the vertex tool (in red) and the geometry displayed by the layer (in yellow) are not in sync

Sounds like you're adding layers in a background thread. This is a tricky thing, you need to ensure the letters are transferred correctly to the mein thread before adding to the project. It's not an issue though, it's a question for stackexchange or the developer list.
