Scenery is doing waves when I move my plane or tank

Hello I have a problem, when I move my tank or airplane, the background (ground, sea , sky) is loading but it’s doing a waving effect. I don’t know what causes this and how to fix it. Does anyone have the same problem or knows how to stop that?

Forgot to say that I tried to reboot my pc, change the graphics and uninstall and reinstall the game and nothing changed.
