I installed Touch of Soul template with two menu tabs. When I pressed menu tab, I noticed that the whole website become white for a half of second and then load the website and page related to the active menu tab. This issue appears only in IE and Safari. As I understand the webpage should not re-load, it should change the text-content (article) only. The blinking is very noticeable and annoying.
