Open GL green color problem

I wrote a simple opengl app. that draws a green ball with a red stripe. I got somehow distorted green color shading ( See Green.jpg attachment.) When I changed the color to blue, things went fine (See Blue.jpg attachment.) Finally I tried yellow (green + red), and I got a more distorted output (See Yellow.jpg attachment). I have a Lenovo ideapad 330, with a discrete/hybrid graphics card: AMD Radeon 530 with the latest stable release driver and an intel UHD Graphics card 620. Otherwise I never had an issue with any videos or images or whatever. Is this a known bug in AMD opengl, or just some hardware malfunctioning of my graphics card. I posted this message earlier on the Communities board but got no reply. Hope can get some leads here...
