Default Screen Flicker

Anyone else notice screen Flicker when the display is on the lowest brightness setting? I am noticing it on the bottom half of the screen usually when the phone first goes into the dim setting (manually or automatically). After it is in the dimmest setting for a while, it eventually stops. Or, if i manually move the setting off the lowest setting by even the smallest amount it stops. I've been running SACS Rom nearly since I got the phone, but the flicker started about 3 versions ago. I'm thinking it may be a hardware issue.
