Cocos Creator version

3.8.0

System information

test on mac 13.4 chrome

Issue description

When changing node of skinned model, webgl keep telling there are unbound buffers.

Somehow we noticed:

  1. when change hairstyle of a human model, node is updated;
  2. skiningRoot setter triggered;
  3. tryBindAnimation in skinning root setter binds gfx buffer to descriptor set;
  4. update -> ensureEnoughBuffers in skinning root setter destroy original buffers but without updating descriptor set; thus error occurred when drawing.

Relevant error log output

No response

Steps to reproduce
