Hi, I'm getting an annoying graphical issue with Wii games in Wii U, it happens that exist a little delay in the horizontal lines, it's between the center and the bottom of the screen, I made a screenshot to show the problem (it's not actual framebuffer shot or game footage).
It only happens in Wii mode, Wii U mode works just fine, setting up 480p doesn't produce this problem, I tested in 2 different TV and It's probably not a problem with the monitor, neither the HDMI cable.
Has someone experienced this problem, I want to make sure that my Wii mode isn't borked or something =/
