Scrolling Panel Editing Lags as More Elements are Included.

Mar 09, 2017

Has anyone else experienced increasing lag while editing a scrolling panel?

I found that as the scrolling panel takes on more elements and/or is lengthened, the lag time while editing within the panel starts to worsen accordingly.

Adding RAM to my machine did not eliminate the behavior. 
I'm running Windows 7 Professional on a 64-bit Thinkpad with 
a 2.4 GHz CPU and 20 GB RAM.

Anything I can do here?

I'm using Storyline 2 - Update 11-1609-3020

I have been authoring locally with active backup to Google drive. But just to be sure, I moved the project to a local, non-synched directory and the lag still persists.

So to be clear, when starting out with a new scrolling panel, editing commands response time is fine but as more and more elements are added (markers, screen shots, text boxes, etc.), editing response time around functions like moving an element around the panel begins to slow to the point of nuisance.

Thanks,

Thanks for that additional information, Bob. I tested this on my end by adding a scrolling panel with a screenshots, textboxes, and markers, and I didn't notice a lag in performance. I'm wondering if there is a particular image on your slide that is causing this lag. Have you tried removing elements one by one to determine whether a certain slide object is causing this?

If that doesn't work, I'd recommend going through these troubleshooting steps and then contact our Support Engineers if the lag is still there. They're available 24/7 to assist!

Understood, Bob. Sorry I didn't make that more clear in my response. Like you said, I was watching for a lag in Edit Mode while trying to move objects around on the slide stage, and I didn't notice that on my end. 

I have seen that behavior before when there is a corrupt image on a slide, so it may be worth removing objects one by one to determine whether that could be causing the issue.

Hello Alyssa,

I am facing the same issue when editing a scrolling panel. All the panel contains is 5x *.png images in sequence (A4 size).

Performing any action on said slide, including moving the pngs around, is taking impossible amounts of time.

Just selecting an element on the page takes approximately 6 -7 seconds. Moving items is practically impossible.

Thanks for posting on this Christos and Phil. At least it validates our experience.

My guess is that SL has to keep track of the positioning of every object in real-time as you  add objects and navigate about the panel. For me,  it slows down no matter the object type, as you increase the length and population of the panel. If it keeps track of every object w.r.t. every other object in the panel then you get exponential lag.

The panel is a wonderful element, works great in production, and we use it liberally. It would be great if SL could find a way to optimize it's real-time editing behavior.

Hi Christos!

Sorry you're experiencing a slowdown! We'd be happy to take a look at your file to confirm that the png files are causing the lag. You can send us a copy of the original .story file by clicking here. 

Also, be sure that you're working from your local hard drive. Working from a network drive or a USB drive can cause a few different problems, and you can read more about that here.
