Bufferbuilder error

i was in my server in the latest snapshot and i was walking around when i suddenly saw this.
the console in the launcher showed that it was a bufferbuilder error and when i rerendered it the visual got extremely randomized the same as i was walking. it was fixen after i closed the snapshot and launcher. not sure if closeing the snapshot only would help to. sidenote: vbo on and the render distance was 12
