I also have small amouts of video noise that is random horizontal lines about 1 pixel tall scattered through the page. I noticed that 14.04.05 uses X server 1.17.2 and 16.04.1 uses 1.18.3. When I do the command xrandr --verbose I see some small differences between 14.04 and 16.04, but it's things like 2 digits displayed instead of 1. i.e. 60.0 vs. 60.00. I'm only concerned with 1080P HD. I've tried this on different computers all with Intel GFX. same results. This does not occur on other monitors or TVs. I'd blame it on Sony and Onkyo if they didn't work so well with Windows, all versions, and Ubuntu all versions except 16.04. It's almost like the auto detection software in the newest version of X is off just enough to make my display flaky. Kind of like the old analog CRT TVs that were sensitive to small tweaks to the horizontal and vertical adjustments.
