Describe the Bug

When I adjust the brightness and contrast, the raster and ghost will appear. The contrast will change, but it will be obscured by the raster and overlap, and going back to the default values will not change the result. I will have to reopen the file to get it back to normal.But nothing happened on the console.

The images are a series of .png images, 1616x970 in size，32 bit. labelme: 5.5.0
