In the latest tag_fw (tried with yesterday's and latest version), the red channel is shifted about 8 pixels to the right (seen from portrait orientation). Tried with multiple tags.

nope... :-( Checked with latest firmware of today.
btw also the black channel is wrapped around a few pixels (see first photo, where at the far right there's one line of pixels that should go to the left of the screen).
Plaatje hieronder is misschien behulpzaam bij het foutzoeken, dan zie je op de pixel precies wat de verschuiving is in alle richtingen. Zwart is 2 pixels verschoven, rood is 6 pixels verschoven.
