Screen flash(like a page refresh) on sidemenu navigation

navigtion between pages works well, however, there a screen flash(like a page refresh) when sliding from one page another page.

Initially had the issue on iphone 3gs and now have the same issue on 4s and 5 - I believe it’s ionic loading screen appearing and disappearing when navigating between pages. how do I stop this?

Thanks in advance,

there was an issue on my CSS… All good!!
