Hi, I have the same problem till today.
Its is very weird...It happens previously with Black,now with Dvha79_ddt.
I think this is not rom depending.
The weird is that....i didn't change anything..just restart the Hermes couple of times(10 and more) and sometimes this solve the problem..strange

))
If you point camera to the dark place...you didn't see these green lines....but if you point to something bright..green lines appear...real strange.
I didn't know the reason for the problem,but I was with Faria clean rom and after mounth of use problem appear,flash with Dvha79_ddt and it didn't solve problem....
Again it strange.
