Comment 1 for bug 1077096

This may be related to this issue:

#1077054 in some cases, sliding the brightness slider to the right (brighter) actually dims the screen more

If the slider "maxes" at 232 when it should max at 255, when you touch the slider and move it lower (left) you may move from 255 through 232 as it moves, thus giving the appearance of the value going up before it starts going down.
