Base layer flickering in HTML5 output

Hi heroes,

I have a few courses with only a few slides. Each slide contains several layers. Each layer contains a video.

When displaying a layer for the first time, I notice a short flickering of the base layer. When displaying again a layer, there is no flickering anymore.

The flickering is of the color of the base layer's background. On the base layer, I only have an audio file for the music to hear on all layers.

The issue occurs in the HTML5 output with both the classic and modern players.

I wanted to start a new conversation rather than continuing the old but useful conversation about Browser Screen Flashes Between Slides. I don't have any issue between slides but only between layers of each slide.

You can see the issue on a published example on Review and the related .story file is attached.

I have submitted a case to our fantastic Articulate engineers (#01507119).

Thanks :-)

Thanks for your support Alyssa, 

Anna could replicate the issue and logged it as a possible software bug.

I'm experimenting a workaround which consists of displaying an image with multiple states on the base layer. When a layer is displayed with a video playing on it, I trigger a state change of that image to display an image of the currently playing video's last frame.

When a trigger displays the next layer with a new video, the image flickers instead of the base layer's background color. So even if it's not perfect, the flickering seems to be less noticeable. 

Until the bug is confirmed and then fixed, would anyone have another idea for a possible workaround ? Thank you :)

Hi Kim.  The issue we identified here was a flickering of the base layer when showing a new layer with video, and it is still an open issue.  It happens the first time you view the new layer.

It sounds like you're seeing something a bit different, though.  When you hide the layer, it flickers the video starting frame instead.  Can you tell me a bit more about your setup?  I'm interested in what triggers you use to hide and show the layers, whether the video plays automatically, and what your layer properties are.

We'll see if we can reproduce what's happening and take some next steps!
