  • Try safe mode (shift on boot), and see if it persists in safe mode. Also try going to recovery (Command-R on boot) and repairing disk. Commented Sep 4, 2015 at 18:42
  • I have the same problem. Happens inconsistently, every couple of weeks or so, after a few hours of use. Mouse is visible and movable but no response to mouse clicks or keyboard. Started happening around 1 year ago before and after updates. Always seems to be on a specific website (well known bank) but that might just be coincidence. Commented Sep 10, 2015 at 17:38
  • similar problem on iMac 5K. After using for a while the applications start to freeze followed by a spinning wheel and: "WindowServer[XXX]: GPU Driver appears to be hung (over 5 continuous seconds of unreadiness)" spread all over the log. To come out of this, changing application focus does help, but it sometimes happens multiple times A MINUTE and makes the iMac completely unusable. I'm on El Capitan. Commented Mar 2, 2016 at 14:46
