Graphics Issue I don't know how to describe (Unstable Branch)

I am running xfce Unstable and for the past few days I have noticed a graphics issue that I don’t know how to describe. It occurs in Firefox and in Chromium as well as in XnViewMP where it is most noticeable in lighter areas of a photo. This issue does not occur on another similar computer running Stable branch. I have tried downgrading mesa, lib32-mesa, vulkan intel etc to the versions on my stable install with the same issue occurring. This is what it looks like:
Photo is from the Mark York story in today’s NY Daily News. Any ideas?

Hi @jrichard326,

Well, I might have an idea, but you’re not going to like it. At all.

I started wondering what I’m supposed to see that’s wrong. Because I couldn’t, still can’t for that matter, see anything amiss.

Then it hit me. And it gave me quite the headache. The fact that it looks flawless to me, on the other side of the world, is quite the clue. Since there seems to be nothing wrong with the screenshot you shared, I think it’s safe to say your problem isn’t software related.

Which only leaves hardware. Specifically your monitor. Or perhaps, if you’re lucky, the data cable. Neither of which we can test for you. I suggest you, somehow, test the cable and/or the monitor.

Sorry my opinion isn’t better news. Hope it helps, though.

Thanks. I see lots of blue spots on the head area of photo. I will check HDMI cable when I get home. Maybe it got loose when I was cleaning

@ Mirdarthos: Thanks so much. It was the HDMI cable that was not fully inserted into the port. I feel embarrassed now.
