Steps to reproduce

被拷贝的texture 为 sprite.spriteFrame.texture

const gfxTexture = texture.getGFXTexture();
const buffer = new Uint8Array(4);
const region = new cc.gfx.BufferTextureCopy();
region.texOffset.x = x;
region.texOffset.y = y;
region.texExtent.width = 1;
region.texExtent.height = 1;

x,y为像素矩阵内的随机一个像素点.

cc.director.root?.device.copyTextureToBuffers(gfxTexture, [buffer], [region]);
console.log(`x: ${x} y: ${y} buffer: ${buffer}`);
cc.director.root?.device.copyTextureToBuffers(gfxTexture, [buffer], [region]);
console.log(`x: ${x} y: ${y} buffer: ${buffer}`);
cc.director.root?.device.copyTextureToBuffers(gfxTexture, [buffer], [region]);
console.log(`x: ${x} y: ${y} buffer: ${buffer}`);
cc.director.root?.device.copyTextureToBuffers(gfxTexture, [buffer], [region]);
console.log(`x: ${x} y: ${y} buffer: ${buffer}`);

@dumganhar 我们也遇到了同样的问题，请问你们有没有新的进展，如有需要我们可以提供demo

[star-e]

@yuwang00 Sure. You may provide a demo, so we can investigate how this happens. 可以提供一个demo，这样我们查起来更对症一些。
