Flashing slides when using actions as navigation in Presenter 9


I have a course with branching where I allow user to pick a path on a screen using actions. However when the user is going through slides in different order, they are in PowerPoint, there is a flash between the slides - as if the slide was not loaded completely so it cannot redraw immediately.

Can you, please, tell me why is this happening and how can I fix it?

Thank you

Hi Elena and welcome to E-Learning Heroes!

Can you tell me a little more about how you're viewing the presentation when this happens, please? Does this happen when previewing, after publishing or both?

If this happens after publishing, are you viewing your published files locally, or are you viewing the project after uploading it to a web server or LMS?

Also, if you're viewing the project from a server, which web browser are you using? Does the same flickering/flashing happen when you view the project in a different web browser?

Hi Elena,

The first thing I would check, just to be safe, would be the DPI settings on your machine. I suggest this since it's affecting your preview and published output of the course. 

Since the issue is happening when you preview, please make sure that your project files are on your local hard drive.

  • Work on your local drive (your C: drive). Working on a network drive or a USB drive can cause erratic behavior, including file corruption, loss of audio, and other unexpected behavior. 
  • You should also make sure the directory path to your project files and your published output is less than 260 characters (for example C:\Articulate).
  • Avoid using special characters, accents or symbols in your file names (this includes spaces and underscores).

Additional information regarding "Naming Files, Paths, and Namespaces" in Windows operating systems can be found in the following Microsoft article.

Now, when you're publishing, it's the opposite. You'll want to make sure you don't view our published output files locally.

If you view a published Studio '13  or '09 presentation on your local hard drive or send it to someone else to view on their local hard drive, you'll encounter security restrictions from the computer, web browser, Flash Player, and network that'll cause various features of your content to fail.

To properly test your published content and share it with others, upload it to the environment for which it was published. Please review the article below for more information:

Hi, thank you and also I apologize for the delay with my reply, but I didn't manage to test all your suggestions earlier. Unfortunately none of them fixed the problem.

I checked the DPI, then I moved all files into folders with short paths, there were no special characters (except within the course itself and the name of the course, but not in the filename).

Then I tested LMS publish in LMS environment and local publish on my hard drive.

The problem, however, persists. It seems to me that it can have something to do with the size of slides (size of background images and other elements on the slide). To explain it better (hopefully): it's like the slide that I'm linking to is not buffered so it can't display immediately. The same thing occurs with regular slides (not only those that I continue to using hyperlinks) when I try to get to the end of the course too quickly (that is: clicking next button as fast as I can). Which I think is not enough time to load the next slide and that results in background of the course to appear first and then to overwrite with the desired content. This was just to explain how it looks. Obviously, if someone is racing through a course, then there's no help. But I would like the course to look seamless when I link to the one of the previous slides.

I don't know how exactly published course works, but I'm afraid that the whole content can't be loaded the whole time, so the browser prepares few next slides to be ready to use, but I'm almost certain, it doesn't take into account hyperlinks within slides and therefore doesn't prepare previous slides at all. Which could cause my problem.

If that's right, is there any recommended maximum amount of data to be used on one slide, to load quickly enough?

Thanks again (and I'm sorry for this essay - I wish I could explain it with fewer words)

Thanks. Since you said that presenter loads slide master and master slide out of sequence, I tried to copy the background image to a slide master, which was previously blank (because I used a series of background images and therefore I didn't use slide master for backgrounds).

And that did the trick. It works now.

Thanks again everyone for help.
