What happened?

使用分块算法放大图片时左下角会出现灰色图块

Steps to reproduce the problem

1. 打开图生图，选择需要放大的图片

2.调整参数，放大2倍，点击生成

3. 生成图片左下角出现坏块

What should have happened?

期望能生成一张完整的图片

Additional information

使用ControlNet里面的tiled也会出现这种情况

我用RX590GME 8GB显卡也有同样的情况，左下角缺失，控制台显示MultiDiffusion到87%就停止了。修改潜变量尺寸也没有改变，而且我用的真实系模型，放大之后遗失了很多细节，产出的画面像是photoshop开了像素化滤镜的效果。改用N卡就一切正常。
