Hi,
I've bought Acer Predator 15 with i7-6700HQ and GTX1070 about 2 months ago. Few days ago I noticed that the touchpad is slightly bugling at the lower right corner. I wrote to acer service and asked if they knew something about the problem, but sadly they did not. I did some googling and found some reviews that also include Predator laptops with exact same bulging touchpad as mine.
A) in this http://www.ultrabookreview.com/12357-acer-predator-17-review-g9-793/ review, bulging is seen here 
in this review https://www.notebookcheck.net/Acer-Predator-17-7700HQ-GTX-1070-UHD-Laptop-Review.223054.0.html , bulging is seen here 
This is bulging that appeared on my trackpad.



Does anybody know what is the cause of this problem and why does it even happen? Is it worth taking the laptop to acer service for repair, if the issue is so common?
