Yeah the DEVICE_LOST error can come from all sorts of things it seems like. As I recall it has something to do with the GPU having a weird response to whatever it was told. Especially odd in this case as you report where it's just happening at random.

Thanks for the report though, hopefully the log can help the devs out.
