Slider does not load properly












0















When you reach the last slide, and turn back to the first slide, there appears a small line on the left side. The image does not fill the entire slide. I think it could be a bug in the JavaScript code, what do you think?



You have a better view of the issue when you have a full screen view, and when you try to resize the screen trying to emulate responsive design.



You can see the following screenshots:

  • Thank you for your answer. Actually it presents the same problem in every browser (Chrome, Firefox, Opera, Brave). Maybe the problem is because I am using Windows 8?... anyways I added a few screenshots.

When you reach the last slide, and turn back to the first slide, there appears a small line on the left side. The image does not fill the entire slide. I think it could be a bug in the JavaScript code, what do you think?



You have a better view of the issue when you have a full screen view, and when you try to resize the screen trying to emulate responsive design.



You can see the following screenshots:
