IE 11 is consuming upto 100% of processor when connecting to website that uses animations RRS feed

  • Question

  • I'm reaching out to see if anyone has heard of this issue. 

    A peer of mine is having and issue with her website.  Anyone who connects to her site using IE11, the Internet Explorer process begins to spike until it ultimately goes to 100%. It's been identified that that animated GIFs and MP4's on the site are the cause. well, pretty sure! :) This affects both Windows 7 and 10 machines, laptops and desktops.  When viewing a page with no animations, all is fine. 

    Using other browsers, all is fine.  So it's specific to IE11 and this sites usage of animated GIF's and MP4's.  

    Going into IE 11's Advanced Settings, Multimedia section and unchecking the option to view animations, has not helped.

    Has anyone heard of this?  Any thoughts or suggestions?

  • Hi,


    The first step in troubleshooting website problems is to test in noAddons mode. However, MP4 content is supported in html5 media elements, but not in Flash ActiveX controls. If you are using a pro or enterprise version of windows the Event View will list the fault signatures of Flash activeX incompatibilities. As a test you could disable your flash installations from Tools>Manage Addons>Show all addons.

    Animated gifs are unlikely to cause problems unless they have been maliciously crafted to include drive by infection. Word-Press websites seem to attract this kind of attack.

    If possible include links to problem websites with your questions. If it is an internal company website please mention as such in your questions.

    If you have not already done so, you should keep your personal computer up-to-date with Microsoft Updates to ensure that you have the latest security patches for IE and updates for Adobe Flash.
