rendering green ball using amd radeon 530 discrete/hybrid with intel UHD 620

gives a weird result as shown in the Green.jpg. Any other color is fine as shown in Blue.jpg. I wrote a simple opengl program to render a sphere with a red stripe in the middle and that's what I get. I even tried using Mesa to render and got the same result. I don't suspect the display since everything else is fine...Is that a known bug or just some hardware issue on my lenovo ideapad 330
