Diagonal pattern on white screen

[PulsarFX]

When I enable the 50% pattern on my 1st gen moto x, I get a kind of diagonal pattern on white areas. The upper part is darker than the lower part. It stays stationary when the screen is scrolled.

I hope the pattern is visible on the Screenshot.

50% enabled:

Off - all is good and in the same white tone.

At least when clicking the images I can still see the pattern/ a difference.

Looks perfectly okay to me. Did you try to open your screenshot on some
other device, or PC? Do you have the same issue in landscape screen
orientation?

It is also visible in landscape, but with additional horizontal lines. I think I have to take a photo to make it visible.

Amyway, it seems that's an issue with display hardware. LCD displays
generally suffer some issues with checkerboard pattern.

Try some display tests in different orientations:

But Moto X has an amoled display.

Okay. Anyway, the screenshot is fine on my screen, and I cannot fix your
screen hardware. Try to set a custom pattern with only horizontal or
vertical lines instead of the checkerboard.

Please have a look and a click on the first screenshot. The exact same pattern is visible on a LCD, too. You have to look at it at 100%. Please don't tell me my monitor is also broken...

This is what I see on my phone with a completely white image:
portrait:

landscape:

I admit I was wrong - I've opened the screenshot on PC, and indeed there is
diagonal line. White pixels have value 246,246,246 on the left, and
250,250,250 on the right. Black pixels have value 8,8,8 on the left and
4,4,4 on the right.
I'll try to improve this.
