Hi Luca,

Sorry for the slow reply. Haven't check the IIS forums for a while, usually I on it several times every day but other things got in the way

No, the PCB is still the same. The Ukrainian PCB has the same issue, although I the effect may be smaller there.
I have tried using other capacitors but the lines did not improve much. Patrice (from French forums) used a larger tantalum capacitor (on Ukrainian PCB) and that helped. However, the capacitor is only rated for 6.3V which is way too close to 6V for my comfort. With the tantalum capacitors I like to have at least double-the-voltage derating.

Having said that, I have found out that the vertical stripes are not an issue, the bias files correct for them 100%. Also the image corners usually get cropped anyway.
