In your case it may be better to use a docking layer instead.The sticky layer monitors scroll events, so if you scroll to the right then it tries to adjust its position. This causes the browser to activate the horizontal scrollbar because there is now an object (the sticky layer) outside the page boundaries...
As ColinM helped me, I moved the sticky layer and other invisible objects (html objects, pace extension, bookmarks) to the left hand of the page.
I also moved the Z order of the sticky layer and it appeared as the last entry of respective page object manager. Then uploaded the page on the server and the problem was solved.
