Most of the time it's norm,but some users report that the phenomenon described in the video occasionally appears.

Thanks for posting the additional info.

Could you please provide more context about the problematic asset:
In the video I can see two leaves on the left which are shown and hidden in a flickering manner.
Are these two flickering leaves two separate skeletons, and should both be visible at the same time (one behind the other for example)? Or is this one skeleton displaying incorrect visibility of attachments?
Are the two leaves frames in one animation, and does this problem occur with only a single animation playing? Or are you playing (overlaying) multiple animations at once, or transitioning from one animation to another?

Could you perhaps provide the problematic Spine project assets so that we can have a look at them? You can attach it to a forum posting or send them to
contact@esotericsoftware.com.

I've sent it to you by email.Thank you for helping me.

Thanks for providing the reproduction assets, we received everything. I just had a look at it, the asset itself seems not to be the problem.

One common issue when updating the runtimes:
Are you sure that after updating the cocos2d-objc runtime you also updated the spine-c core runtime as well, and copied the contents over to the respective directory as described here:
https://github.com/EsotericSoftware/spine-runtimes/tree/3.8/spine-cocos2d-objc#usage

If you are sure both cocos2d-objc and spine-c are at the latest state, could you please send us a minimal cocos2d project where this issue still occurs? Thanks!

Hi, This problem still bothers me. I've reproduced another phenomenon in demo.
Problem description:
When loading scenes, scene elements are often missing.Our APP has 200,000,0+ users, and this problem occurs frequently.
There will be problem scenes at the beginning of the video and the 25th second.
Cocos2D-ObjC version 3.5.0; spine runtime version cocos2d-objc 3.8; spine version 3.8.95.

I sent the demo and video to contact@esotericsoftware.com ,hope you can help me.

Thanks!
