Default RAZR Maxx xt910 weird screen

i dont know this is common problem or not,
but my screen kinda weird since i've 'jaibreak' from stuck in boot loop.
my screen seem to be yellowish. dont know hoe to fix that.
but, i can see my ics keyboard's shadow even i'm not typing or slide out my keyboard.
another was the top, where browser search bar located, that area doesnt have yellow tint.
watched a video in Youtube in full screen can see clearly which is not yellow or not
elp me, is there any kernel screen tweak?
because on my atrix, i'm able to tweak my screen temp/K
