You problem looks very similar to mine, but my corruption begins futher to the left in my images. I have been discussing it under the \"Strange Lines through Image\" topic.
This looks like a exposure while chip is still reading out data.
If this is the case there is something allowing the H2 capture before P20 is ready.
So we can solve this, please do following:
1. Go to
http://support.phaseone.com/Global/contact_support.aspx 2. Create a Support Case
3. Attach the RAW file to the case.
4. Include following firmware information in case notes:
A. MAIN version of P20
B. PAVR version of P20
C. Body version of H2
D. Lense version of H2
