I can confirm that this issue seems to be resolved for me as well. Sometime between my last point 1/17 and David's post an update fixed my MacBook. I see I've installed updated lots of packages including X, xserver, and the kernel, so not sure exactly what update fixed this bug, but "WFM".
Can others on this notification list please re-test (to confirm the problem) and then apt-get update/upgrade to see if the problem goes away?
