What is this line when zoom on wheel ?

[znw-test]

When I zoom the image with the scroll wheel, there is a high probability that a line will appear. Can anyone tell me why this line appears?

system: Mac OS 10.15
browser: Google Chrome 105.0.5195.102

Is your computer running out of memory?

Thank you for your answer. I think there should be no out of memory. I think it has something to do with the browser.

In this demo, I clicked cropper.clear() first and then used the scroll wheel to continuously zoom out and zoom in on the image. This problem is not obvious on Safari browser but it is easy to appear on Chrome browser

I think I've found the solution to this problem. This problem is more pronounced when the background is a solid color.

When I added this attribute value to the image, the problem no longer appears in Chrome.

.cropper-hide {
    backface-visibility: hidden;
}
