seems to be dependant on horizontal resolution. I could reproduce this
with tvtime depending what horizontal input resolution was selected
(need to check, but I'd guess that's what it will use as xv size). For
me the flickering line was at the left, though (since the uv planes are
shifted a mess at the right or left is bound to happen). Guess there is
some rounding error somewhere when calculating the start pixel of the uv
planes of the overlay...
