If it's helpful (or for someone to point out that I'm doing something wrong) here is a quick screen recording creating the issue I see. Apoligies in advance for the terrible chord progression

Today I am noticeing that even if nothing is playing.. If I hide the VEP window, showing the DP window...CPU is pretty idle at 3%. Show the VEP window and hide the DP window...CPU usage jumps to 15% and stays that way..nothing is playing.
VEP is clearly doing something with the GUI that is using up 15% when nothing is happening. I hope you can get to the bottom of it.
Today I installed the update from this morning and performance is horrible, worse then yesterday, can't even play from Cubase at all without dropouts, DP only slightly better, Logic still plays it because Logic is somehow more efficient. But all three exhibit this problem of the extra 10-20% cpu when VEP window is showing.
