We are using CMS version 2.26.16 because of
CMS7-9145. With 2.26.16 issue CMS7-8980 is fixed as well. As a side effect this issue introduced scrollbars in the CMS. See attached screenshots (Scrolbars-chrome.png and Scrolbars-IE8.png).
Problem cause: The fix for
CMS-8980 makes a change in the gallery-wrapper, this name is also used in the Images tab.
