Yep its a freed or trashed surface.
I saw this bug while I was developing.
And it seems I fixed it for me but not for anyone else.
I'll keep trying to replicate but until I can get it you will have to trace.
Google for the watch command for gdb.
And maybe try efence or something to see who is trashing it.
Whats your bit depth ?
Damn
