I can reproduce this issue with the demo. A few notes for myself:

*) When disabling ARB_map_buffer_range but enabling dynamic buffers the bug
goes away
*) There's no multithreading involved
*) The game uses only dynamic vertex buffers, no dynamic index buffers
*) Rebinding the stream sources every draw does not help
*) GL_MAP_INVALIDATE_BUFFER_BIT causes the issue
*) No double maps(lock_count is never > 1)
