Australian Open: Dead Spot on Hisense Arena

During the warm up for the match of Maria Sharapova and Julia Goerges, Maria had walked over the court (near the net) for the coin toss and felt a little extra padding. It turned out to be an air bubble underneath paint job on the court. The reason behind this was later stated to be because of Melbourne's hot weather (hot court) that caused a flat bubble patch on the plexicushion surface.

As you can see in the video at 0:40, the ball does bounce AT ALL on the "dead spot". This problem was solved by using the drilling holes in the area to let the trapped air out. This was the first time a dead spot has been discovered, so what do you think? Is it probable that more may be found in this hot weather (not even record high, or humid)?
