IE11 popup flickers when dropdown menu item is clicked

I have a popup which has a download icon. The download icon is a link within menuitem, on clicking of which two submenuitems are shown to the end user which are "PPT" and "PDF". Basically, we are giving two options for download to the user- download PPT file or PDF file.

Specifically on IE11, when I click on the download icon, the complete popup flickers. The popup is not reloaded (I am sure of this because the preparation doesn't run again). It just flickers. The same thing happens when I click on either the PPT option or the PDF option.

This doesnt happen on the chrome or mozilla browser. There is no error on the console as well.
