Have you rebooted?
I have not seen this as a general problem. However, I have noticed the computer gets slower and slower the longer it has been since a reboot. After 4-8 hours (based on the spin reports that are piling up
) apps start responding slowly to HID events. And the mac starts creating spin reports with the reason "Slow response to HID event". I currently have 61 spin reports since installing beta 4.
I haven't submitted feedback yet, because I think the spin reports are automatically sent to apple, but I think I will anyway.
