Storyline Glitching

Whilst i'm using storyline, the view of the canvas i'm working on glitches everytime I move something around, wether it's a text box, image etc the white canvas disappear and then comes back for only a split second but it does this everytime I interact and it's becoming quite difficult to work around. 

I don't think it's the file size as it happens on brand new projects and large projects, I have the most up to date version too so i'm not sure what could be causing it. 

Any suggestions on how to fix this?
