I see that you're a new member...Welcome.☺
The effect you refer to is simply the distortion caused by wideangle lenses, worst on anything at the edge of the field of view with the camera tilted, as in your second photo. A poster in the G3 forum observed exactly the same effect and posted the same type of photo as yours, long ago. Minimise it by holding the camera square-on and at head level.
I noticed in one of your other posts that you had a troublesome G3. Some owners do, and indeed that may possibly be true of all devices, but I suspect they're in a minority....my own G3 is trouble-free and much-loved.
