sequential image stitching getting blurred

[kxg3030]

Hello, this library is great. I am planning to apply it to my project, but I have found some issues and would like to seek help. My application scenario is to continuously capture images from the screen and then stitch them together in a loop. I found that as the number of stitches increases, the previously synthesized parts become increasingly blurry, while the newly stitched parts do not experience this situation. I found a similar problem online: https://answers.opencv.org/question/54891/sequential-image-stitching/

Is there any way to solve this problem
