When the program is doing background rendering, it will go to 100% CPU time, but once the background rendering completes, it should settle down to almost no CPU usage at all (my task manager literally shows 0% CPU once pre-rending completes).
Does this high CPU usage happen even when you don't load a PDF?
After loading a PDF, there will be a small progress bar that races across the bottom of the presenter window. This represents the pre-rendering process. Does the CPU usage lower after that process completes? (If you need to run the experiment a few times, note that pressing Ctrl-R will flush the cache and re-trigger pre-rending.)
You are right, it is the background rendering. I accidentally re-triggered it multiple times by re-sizing the window. Thanks for your explanation!
