Hi,
I have noticed that my MBP's(W8612******, SMC 1.2f10) screen winks withing 2-3seconds of waking up. The wink is almost the same as an old TV does when changing channels (mine is more than 10yrs old, so don't know about new ones). I don't think it did this blinking before the 10.4.6 update (just after I got it and tested without the upgrade).
Does this happen to your MBP or is it only me? Should I call up Apple? (this questin is kind of a fashion now)
Thanks
