I was able to verify this locally on my windows machine with 175% scaling. Example of blended capture: <img width="300" height="300" alt="SourceClippingBlitTest" src="https://github.com/user-attachments/assets/dce39a02-1471-4459-be99-3217e1036a66"; /> I have updated the test to not check these intersecting pixels. The current form of test is reliable and verifies blitting with source clipping properly. ------------- PR Comment: https://git.openjdk.org/jdk/pull/32904#issuecomment-5713024985
