This started happening a few days ago so I guess its related to the Windower 4.3 update. Anyways, I noticed that the image on the screen will lighten or darken randomly. When it happens its pretty subtle, not like hitting F11 key. But, the overall image will get a little brighter or get a little darker.
Its kind of hard to describe. I asked some other people in my linkshell yesterday about it, and today people are telling me that yeah they are noticing the lighten/darken effect too.
Anybody else noticing this?
