High CPU and log spamming

EddieMa · 08-15-2015, 04:08 PM

I have this problem too -- it hits the log whenever I switch desktops (spaces) in the DisplayLink displays -- or if I activate a window in a DisplayLink display.

(I'm running a pair of LT1421 displays using a MBP 13" 2012, if that helps -- and this happens with/without a usb hub between my MBP and the displays.)

Here's a sample of my log.

Please let me know if you need any more information to debug this.
