Pasting a screenshot through the clipboard corrupts the image
When i try to insert a screenshot through the clipboard on google or yandex image search, the original image is corrupted. Even i try to upload an image via classic upload-button the same problem reproduise. On other sites there is no similar problem, as well as trying to insert the same image but inside the application windows.
In attachement: yandex/google and default image i was trying to upload.

What security software are you running besides MS Defender? Are you running pro version of Windows? If so, you should have Windows Sandbox enabled for testing. https://www.howtogeek.com/399290/how-to-use-windows-10s-new-sandbox-to-safely-test-apps/

I dont use any security software even MS Defender. Im on Win 11 IoT LTSC 24H2. In troubleshoot mode i have the same issue, nothing changes. I think maybe it happens via recently BIOS update for my laptop, i will try to downgrade to see the difference.

Yes, that was a point! Now it works. Could you explain please how does it makes sense?
Users enable `privacy.resistFingerprinting` and then are surprised when it adds a random noise to images to prevent canvas fingerprinting.
