How do you get rid of this noise?

I slipped the old gsdx of 2015, everything works fine with it. resetting the settings gives nothing. 
Am I the only one who has this problem with the latest builds of gsdx?

This is called dithering. It is a normal effect that was skipped for many many many years but just recently added to the hardware renderers (it's been in software all along). There's a hotkey, someone will need to correct me if I am wrong, I think it is Page Down to change it. You'll see a message print in the console when the dithering mode changes.
