Lightbox flickers when opened

Jun 17, 2019

I'm having an issue where lightbox slides flicker/flash white when they are opened. Has anyone experienced this before? 

I'm running the latest version of Storyline 360. Published to HTML5 and viewing in Chrome.

I have the same problem--I haven't even tried publishing yet, but it does this in preview. I thought it was because the lightboxed slides were white underneath dark content, but changing the background fill to black didn't help. I even tried going into slide master and changing the backgrounds on those particular slides.

Hi Heather,

Thanks for reaching out, and I'm sorry you're running into this issue. Just to confirm, we do have a bug reported where:

Lightbox slide shows a white space and flickers when loading in the Classic Player.

We don't have this reported for the Modern Player, so that may be worth trying if possible. We're still monitoring the impact of this bug, so I appreciate you letting us know that it's affecting your projects, and we'll be sure to update you with any progress.

Hi Heather,

Thank you for letting us know! As Ren mentioned, we haven't been able to recreate this issue while using the Modern Player. With that said, would you be able to share the file that is experiencing this issue for further troubleshooting? That would help out greatly to see if the issue is potentially more widespread. 

You can share files in this thread here or you’re always welcome to share them privately here. We'll let you know our findings and will delete it after having a closer look!

I am having this issue as well using v.3.43.22859

Every lightbox action results in a white flash before the content of the slide appears. This is especially evident when using a transition (like fade or zoom). When no transition is applied, the flash is quick. 

This bug is killing the transition effects (ie. if I wanted a lightbox to zoom into view for example)

Hi Tom,

Thanks for letting us know you're running into this too, and I'm sorry it's causing issues for your course! I'll be sure to share those additional details with our team that transitions cause even more obvious flashing.

To update the conversation, we've discovered that the lightbox flickers as well in the Modern Player as of Update 40.

I'm sorry I don't have a timeframe for a fix, but I will be sure to jump in here when there's any progress to share.
