I have a 2012 MBA 13" i5 8 GB RAM. Since the last firmware update, my display flashes or flickers a thick white horizontal stripe across the top half of the display, whenever I minimize a window. This happens when connected to an external monitor and also on the native display on the MBA. Has anyone else encountered this?

nope

13" MBA 256 2GHz i7 - no flashy for me. I run standalone and with a VGA monitor attached, 1440x900. I've had nothing but love from my dear sweet airluminum.

yep, similar problem

2011 MBP, since the latest update this week I'm getting screen corruption at random times. seems to be mostly in the mail app

would love to hear that this is a common problem related to the update and not my mbp on the way out......
