FWIW, your link gives me only Cannot GET /spine.html but I see the screenshot of the problem.

Please see the compatibility notes here:
spine-runtimes/spine-ts at 3.8

spine-ts Canvas does not support color tinting, mesh attachments and clipping. Only the alpha channel from tint colors is applied. Experimental support for mesh attachments can be enabled by setting spine.canvas.SkeletonRenderer.useTriangleRendering to true. Note that this method is slow and may lead to artifacts on some browsers.

sorry! I changed url to http://spreatics.com:3000/
plus, I solved the problem with SkeletonRenderer.useTriangleRendering = true
Thanks a million!

Experimental support for mesh attachments can be enabled by setting spine.canvas.SkeletonRenderer.useTriangleRendering to true. Note that this method is slow and may lead to artifacts on some browsers.

Note that this feature in spine-ts Canvas is highly experimental. Pretty much only Chrome renders triangles correctly. Other browsers will show sampling artifacts. It also causes a slow down. If you can, switch to spine-ts WebGL.
