3 devices, all rooted. same issue on all

[subzero1313]

I've had an Evo, Evo 3D and Tab 10.1, all rooted. Ive noticed ocassinally my back light doesn't totally dim unless I hit the lock button. All 3 devices do this. The Evo was on OMJ, the Tab is on bonsai and the 3D is still stock.is this some side effect of rooting that I never read about? Or does anyone know what causes this and how to fix it?
