White box covers portion of slides
Apr 17, 2020
We're seeing an issue with Storyline 360-produced SCORM packages on mobile devices and I thought I'd ask if others are seeing this issue. You can see the issue in the attached screenshot. An opaque white box will randomly appear and cover half of the slide. The portion of the slide that continues to be visible functions normally, but the portion that is covered by the white box allows no interaction.
We're seeing the issue with all of our modules and it appears randomly. We don't see a pattern or steps to reproduce the issue. The issue is only happening on mobile devices, Android and iOS, but more frequently on Android. We don't see the issue on PC or Mac browsers. When viewing a course on a mobile device, we're usually swiping through the slides, which might provide the best clue. The workaround is to close and reopen the course.
Is anyone else seeing this issue?

Hi Jamey,
Based on the image you uploaded, it seems to be similar to an unresolved notification or pop-up on the mobile browser. Let's see if we can get to the root of the issue.
Does it only appear when running Storyline packages only and not on any other page?
Does it occur while on mobile data or while connected to Wifi?
Are you able to download the package and run it offline and see if the issue occurs?
Do you have any browser plug ins or apps that appear "always on top" such as assistive touch or screen capture apps? (You can try disabling them and see if the issue still occurs)
Is the issue occurring only on Chrome or is it persistent on other browsers as well?
Looking forward to hearing back from you.
Hi Jan,
Thank you for your questions. Let me respond for Jamey, as he no longer works with us.
Yes, it only happens with Storyline packages, on both mobile data and Wifi, even if we use the Moodle app to download the SCORM package and play it offline. I personally do not have any of the assistive touch or screen capture apps open. It seems to affect Chrome and Safari, I have not tried other mobile browsers.
Since we have never experienced that issue on a desktop, and we tested a lot - I wonder if it may have something to do with functionality unique to touchscreens (i.e. swiping) or mobile versions of browsers.
Kind Regards,
Martin
Hi Martin!
I appreciate you sharing additional details with us! We'll help get this snag figured out.
We don't have any recent bugs that are similar to what you're seeing with the display of the course when viewing the SCORM package on a mobile device.
Let's start with viewing the course using a different LMS. We use SCORM cloud for testing, which is a free industry-standard testing engine. Here are the steps we take.
If your course is working properly with SCORM cloud, then we'll look into LMS changes!
Hi
I have been experiencing the same issue with my courses.
The course works fine on PC, but on the Samsung A Tab that our users use, a white box appears on top of the content on random courses.
It would seem like it happens if you drag or zoom on the screen in some of the cases.
Also, in one of the courses where I have changed the background color (in the CSS file), every time I push a button in the course- a white box blinks (but then disappears again) at the same place the white boxes use to appear. This also does not happen on PC.
As you can see in the attachments, the white box can appear on both the left and right sides of the course.
Hope you can figure out what is causing this bug.
Best,
Anette
