后台运行问题

点击生成图片按钮后，老是跳出后台运行界面，生成进度变化一次跳出一次。在不同的菜单栏都是这样

The issue describes a UI problem where a background process window repeatedly appears during image generation. Start by locating the 'generate image' button event handler and the code that manages background tasks or progress updates. Look for modal or window management logic that might be triggered incorrectly. Reproduce the issue to see the exact behavior, then trace through the UI flow to find where the unwanted window is being shown.
