I remember a similar issue when i reworked my sync shifter.
The LM1881 preamplifer gotten a too strong signal (i guess) because i used the wrong resistor and i made another mistakes in the NE555 'chain'.
This only happened with my SNES, my N64 and GC didn't had that problem despite that these were the same signals.


Now as the scanlines shift to the right after the white lines means that the sync circuits 'senses' the sync pulse too early.
I guess this is some AC coupling issue as your sync source (luminance) also carries the brightness and this seems to effect the sync separator, normally the video signals for consumer displays should be AC coupled (except for VGA), also should not have a DC voltage offset (except for VGA).
Now the good question which console it is and if there should be any AC coupling capacitors in the cables.
