Please provide a full example to allow us to reproduce this bug if any. Maybe there is something obvious that we miss. I advise you to create a more simple example with just a single triangle. In my humble opinion, there is something wrong in the creation of the VBO in ImmModeSink, maybe the passed parameters are wrong.
