Hi guys and girls 
I’ve a really weird display issue in the scene and game tab:
I can’t remember any action which could have trigger this… My display driver is up to date, 3D is activated, graphics settings are on “Fantastic”.
If somebody can help me, please…? 
Thx a lot !

Been a while since I’ve looked into graphic issues, but I’m pretty sure that’s a Z-Fighting issue (nothing wrong with your actual display adapter).
More info with possible solutions by Jessy Catterwaul here, a few years old but I think it’s still good.
Basically, when rendering there’s a depth buffer that’s used to determine what pixels projected from whatever is in your scene should be rendered infront/behind whatever pixels have already been rendered by writing and comparing their distance from the camera using the aforementioned depth buffer. However, the range of values that can be stored into the buffer is limited and (I think) evenly distributed along the camera’s view frustum which, along with rounding errors inherent in the calculations, will result in the kind of artefacts that you are seeing - especially when using a very far clip plane in the camera.
Try bringing in the camera’s far clip plane closer and maybe pushing its near plane farther out and see if it doesn’t minimize the errors. Other than that you might have to change your game’s scale and maybe start looking at shaders or other creative solutions like multiple cameras or layers with explicitly set rendering orders.
Someone else might be able to give you more specific help, but this should get you started at least.
Yeah, it looks like z-fighting.
Have a look at how deep the water is. Try making it deeper and see if this changes anything.
