Canon G7X macro really bad

Re: Canon G7X macro really bad

As you can see the detail in the second image at the centre is much sharper.

Does this indicate there is something wrong with the autofocus on my camera? Or maybe with the G7X autofocus in general?

This probably isn't your problem, but it reminds me of a fun bit of trivia.  Canon calibrates each lens at the factory and then stores the values in FLASH memory on the image processing chip.  This includes an offset for the auto focus. 
I know this because I repaired an S100 with the 'lense error' problem by transplanting the whole lens & sensor assembly from a different S100 with a cracked screen.  That fixed the lens error and it appeared to work great from the small screen, but all the pictures were a bit soft at full resolution.  Going back and transplanting the main PC board fixed the AF problem.
If you bought your camera 2nd hand, someone might have done a similar repair without realizing the lens/sensor assembly and camera control chip are  matched set.
