Very blurry text and images in Chrome HTML5

I am using Storyline 360 and publishing HTML5 only. My client uses Chrome only. Every image and all text is unacceptably blurry.

Attached is an image of a screen from the course. On the left is HTML5 in Chrome, and on the right is Flash. Even the "Next" button is blurry.

I see in other discussions that this is a known issue. What is the timeline for fixing this? I will no longer be able to support this client unless we can get a fix soon, as they are quite dissatisfied with the current state.

We have tested the HTML5 output on IE, Safari, and Chrome and the only times we get quality issues is with Chrome. We are trying to determine if this is an HTML5, Chrome, or SL issue or a combination of one or more of those. We are in the middle of upgrading our LMS to Docebo, which only supports HTML5. Is this a SL3/SL360 issue or is it an issue outside of the authoring tool? The answer to this will help us determine if we will upgrade from SL2 to 3/360.


Dear Ashley, a few more details to help the diagnostic. I have no animations. I just opened a new project with only one slide with title and text content. When I type in text I can already see the text is blurred compared to what it used to be. Preview is very blurred, but the PREV and NEXT buttons seem not blurred. Published content is blurred in Chrome but looks normal in Edge. The same file opened with Storyline 3 looks OK, both in editing and in preview. I hope this helps.

Hi Pauline. The blurriness we're seeing is a combination of Chrome and Storyline. Our next update to Storyline 360 will add enhanced support to address the blurry issues we've seen in that browser. We'll let you know when the next version is available! Storyline 3 will get the same attention after the Storyline 360 update is released.


I have exactly the same problem, as reported earlier. Operating System: Windows 10 Pro, Version 1809, OS Build 17763.379.  Display setting 1920x1080, scaling 100%. I know you are working on this, and we all appreciate it.  Is there any information about when to expect a fix? Or a workaround until the fix? I need to publish the courses by certain deadlines and the blur is blocking this. Thank you.

Hey everybody. I'm excited to let you know that we just released update 26 for Storyline 360! Here are all the details.

We addressed an issue where text and images could be blurry when viewing a course in Google Chrome or Safari.

Here’s how you can update Storyline 360 to take advantage of everything the latest release has to offer. If you need more help, please let me know!
