PBuffer and gray lines through JPEG

JPG files have gray lines through them.
These lines appear regardless of the resolution settings or profile used, but do not appear if I use Publisher to create a HLR JPG image.

This problem could be related to the PBuffer parameter .
Have a look at Publisher’s .
It depends as well on the size of the MVP window (different size/nb of grey lines depending on the size of the window)

Unfortunately, you cannot set this parameter through Sync.

So, either you have Publisher installed on the same machine than Sync, and then life is easy.
Or, you can try to add/modify the key manually into the Registry (with care … of course)

HKEY_CURRENT_USER\Software\seemage\MVP\Preferences

Keys are :
HardwareSupport.PBuffer and HardwareSupport.PBuffer.Static
Set to 1
