I made super simple code: spawn mixandmatch actor randomly.

and on spawn time, it flickers on single frame. (Played in editor)

Did you set bones and slots to setup pose? It looks like the first frame doesn't have its bone transforms calculated. See spine-ue4 Runtime Documentation: Resetting to Setup Pose

@Mario I tried setup pose nodes, but it works little, just feels like frequency decreased

my code is below

Did you wire up the tick event as described here? spine-ue4 Runtime Documentation: Spine widget for UMG UI

That is responsible for calculating all the poses after applying the animation. You can also call it after set animation on the Construct event chain.

@Mario It's not umg. it's an actor. so it doesn't have tick node.

Ah, apologies! You can directly call the Update world transform node: https://github.com/EsotericSoftware/spine-runtimes/blob/4.0/spine-ue4/Plugins/SpinePlugin/Source/SpinePlugin/Public/SpineSkeletonComponent.h#L80
