I'm sorry if I created the theme in the wrong place. I'm asking for your help.
I play spine animation with this script https://github.com/EsotericSoftware/spine-runtimes/tree/3.6/spine-ts/widget.
It works great. But some animations have artifacts on playback. Temporarily it can be seen on this page http://mvs-web.ru/4/index.html.
The third and fifth animation is the same on different backgrounds. That's the problem with it.
Can you please tell me what you can do about it?

Are you exporting your texture atlas using premultiplied alpha? If so, you have to tell the widget that you use premultiplied alpha as well using data-premultiplied-alpha="true".

Thank you so much for paying attention to my problem!

I added the corresponding parameter to div, but it had no effect. On the specified canvas page with the parameter last.
Maybe you have more ideas?

I get a PNG file from ktx using Mali Texture Compression Tool v4.3.0. I don't know how it converts texture.

Here is a link to the original texture file, perhaps this will help

Could you please try your example without the Mali Texture Compression? I'm afraid I'm currently away from my development machine, so I can't test myself.

The original image files are in ktx format, not png. I haven't found any other programs that can convert ktx to png, so I can't do without the Mali Texture.
Perhaps you can tell us the best converter .ktx->.png?
I'm sorry if my tone of response seems bad. My English is bad.

I found a solution to the problem. The problem was in Mali Texture. The program has crookedly converted files.
Now I use PicoPixel to convert ktx to tga, and from tga many converters to png. Now the animations are played back as they were meant to be!
@badlogic, thank you so much for the tip, you were right!
