IE 11 should be working with Tableau Server v10.x. I suggest opening a ticket with Tableau Support to help reproduce the issue and verify if it is a defect that needs attention. Visit http://support.tableau.com to begin the case submission process.
please be sure to submit the version of Tableau and IE that are in use.
Also - here is the article about supported versions of IE and Tableau With Tableau 10.0, we’ll stop supporting older versions of Internet Explorer | Tableau Software
IE 11 and greater are currently supported but be aware of older versions that may be unsupported and have incompatibilities.
