Articulate Storyline 2 - CHROME 48 - story.html5 - Flashing issue - D2L


We are wondering why the story.html5 output is having issues displaying correctly in Chrome 48 on PC only.

The package is sitting inside of Desire to Learn LMS and is showing the following issue:

Flashing, almost like it is constantly trying to resize the object. 

Has anyone out there had this issue ?

I understand that common practice is to deploy the story.html and rely on the auto-redirect which points to the story.html5 version upon device recognition. 


But I am wondering why the story.html5 version is not working in chrome by default as well. I the .html5 version only compatible for mobile devices and not desktop ?


Thanks in advance.

Hello, All -- I just wanted to stop in and share an update on Nick's case from our Support team, as it may help others who come across this post in the future seeking assistance.

Our engineer, Jayem, suggested the following, as it appeared in screencasts provided that the html5 version was continually trying to adjust its size while in his LMS environment. Based on that observation, here are the proposed workarounds:

"Try adjusting the Player size property from "Scale player to fill browser window" to "Lock player at optimal size"? This option can be found by going to Home > Player > Other.

Launch the project in its own environment. To do this, please go to Home > Player > Other and check the "Launch player in new window". When trying this method, please double-check with your LMS administrator if the tracking will still work."

In addition to the update shared on Nick's case, below is the response that was sent to Riccardo, as provided by our Support Engineer, Miker. Hopefully these updates are helpful too others in the future! :)

"Hi, Riccardo -- When you use Google Chrome 44 (or later) to view Articulate Storyline HTML5 output, you may find that slide content is missing. This issue was fixed with the release of Storyline 2 Update 6 (and Update 7). 

To fix this issue in published courses, run the Articulate Updater for Chrome to automatically scan and update your course files. 

 Let me know if you need anything else!"

To complete this post I can report back that the proposed solution works

Desire 2 Learning has too many quirks / limitations to mention, but this
solution will restrict the size of your canvas as Desire 2 Learn only has a
maximum embed size of around 720px WIDE. Anything past this will activate
the horizontal scroll bar which is not ideal.

Many thanks to the articulate team for the fast results driven turn arounds.
