Experiencing strange screen effect in games and desktop

[DigitalPixel]

Sometimes I see this effect in games and even on the desktop. It's difficult to capture with camera but here is the best I could do. Look to where the trees start near the middle not the sky as those are just pixels close up. I really need to be up close to the screen. I'm seeing horizontal lines but very faint. Almost like a screen door effect. I first noticed it in RDR2. But as soon as I hit the ESC key to pause the game and then go back it disappears and the image looks smooth again. It kind of looks like interlacing lines. This is on a LG 34" UltraGear monitor with a Strix 2080Ti GPU. Everything is up to date so I don't know what is causing this.

Hard to tell by the photo but looks like it might be some dead/stuck subpixels. Use something like this test:

Cycle through the white, black and RGB screens. If you see any areas not lit up or the wrong color, that's the problem.

No its not dead pixels. This effect goes across the screen. Like I said if I hit ESC in game (RDR2) and then go back they are gone. On the desktop I noticed them in the title bar. But if I restore down/maximize the window it goes away.

Hey,

I know this is an old post but did you ever find a solution? I think I have the same issue as you where outdoor areas seem to have a screen door effect and no in game settings are the cause.
