Browser Screen Flashes Between Slides

Hi,

we're building a short interactive quiz with Storyline 360. It's very important to us that we have smooth transitions between slides. However, upon testing on different browsers we have experienced white flickering when the next slide is loading. There is no transition effect between slides, all objects are aligned to timeline start (0,00 sec) and there are no animations on individual objects. We are testing on Articulate Review, exported to HTML5 with FLASH fallback.

Can this be fixed?

These are our testing results if that helps:

MAC Chrome - no flicker

MAC Safari - flicker

MAC Firefox - no flicker

PC Chrome - no flicker

PC Firefox - no flicker

PC IE 11 -  flicker

PC Edge - flicker

iPAD Chrome - flicker

iPAD Safari - loading dots with short flicker

Thanks in advance if anyone has figured this out.
