Recently I found this bug where the playback goes more “slower” for large sequences when the speed is set faster. For smaller sequences, in the playback it switches to the next images quickly within less than a second. But for large sequences (around \>150 images) it takes 2-3 seconds to switch to the next image when the speed is set faster. On the other hand when the speed is set slower, it switches to the next image faster, although the image transition effect is slow.

Thanks for reporting! I’m looking into it now and I can’t really reproduce it on my end so I would need a bit more information to aid my debugging.

1. Which platform do you experience this? Android, iOS, or web?
2. Do you have a link to a sequence so I can reproduce the issue?
3. How fast is your internet connection?
4. Are you using “play” or are you stepping manually?

Thanks!

This issue should now be resolved.
