When I attach my Samsung Galaxy Note 3 Sview case my phone slows down. Has any one experienced this?

After getting an S-view case for my Note 3, I noticed many of my apps slowing down during use.  When I remove the case, the phone acts normally.  Also, when I go to the sview settings to add weather, it prompts me that settings has stopped working and it does not add weather to the s view.  Has anyone experienced this or know of a fix?
