Slightly doubled image

Hi everyone, those who have this problem – could you please help us identify the reason behind it?

Could you please roll back to the previous firmware V1.1.04 by following the instructions INFO: How to do offline software update?, but use the following firmware file – PPX620 software V1.1.04. Don’t unzip it, just rename to update.zip.

Does the problem disappear then?

Note: downgrading will not erase your settings.
