Artifacts in Objects and meshes in viewport V2.81

Can anyone please tell me how to remove these artifacts in meshes and objects in the viewport. It happens with any mesh or object I place whether it’s a low poly or high. This has never happened to me in other versions. I’ve tried all the render Engines but nothing changes. I’m sure is some setting some where but I don’t know where it could possibly be. I have dual graphics card and a pretty high end computer. GeForce GTX 980 TI and Intel Core i7 6700K CPU 4.00GHZ if that matters

Thanks you!
