My unibody 15" MBP has excessive light bleed, at the sides as well as the well-known "stage lights" effect at the bottom. I notice that, if I flex the lid ever so slightly, the bleed effect, particularly at the sides, either increases or reduces quite dramatically according to the pressure. The effect reverts to its original level of bleed when the lid is released. This leads me to believe that the problem is related to the screen being flexed by more than an ideal amount by the sandwich of lid and glass. This would mean it's a design/construction problem, rather than a screen QC issue. Opinions?
