Note these are seperate issues, caused by the same underlying issues with float precision. Some game engines solve the jittery rendering issues by moving the world relative to the player/camera, rather than the opposite (though it may be more intuitive). This way all your shaders work in nice accurate low floats relative to the camera at the origin, no matter the player location in the world. But to implement worldgen with relative coordinates would be much more complex.
