SUMMARY

When zooming into my PDF File i can notice a fast and very substantial increase
in ram (see attachment) and CPU usage.
I'm using the "greedy" memory usage setting, but a friend could reproduce it
with default settings, if not as severe. 




STEPS TO REPRODUCE
1. Open pdf (will supply the pdf used in attachment) 
2. zoom in (min 400%, the more the worse the result)
3. huge ram usage
