Setting max_flush_vertices to 1 fixes the problem here, with the mentioned noticeable performance loss. IIRC, hibernating/resuming can accelerate the appearance of the bug, but I'm not quite sure about this, it might also be coincidence.

I will now try to decrease the value from the default one to find the sweet spot.
