Hi Mario, I've just done some testing on a single screen here and get a crash as well after interacting with the scene for around 30 to 60 seconds. I've just force single threading via the OSG_THREADING=SingleThreaded env var setting and so for it's not crashing.
My guess is that this crash is unrelated to Mathias changes and is a general threading issue, but... one can't rule anything out at this stage. Robert.
