This test verifies whether the frame is maximised or not by checking its four border points(by comparing it's colour with GREEN). But in OEL, the top left and top right borders are curved, so there is a possibility of error if we directly compare those points with GREEN colour, that's why an OFFSET is needed. But an OFFSET of 2 is not sufficient for OEL, and for safety I will change it to 5. I don't see this issue in Ubuntu as the borders as rectangular there, but not curved. I'm attaching the OEL screenshot for your reference.  ------------- PR Comment: https://git.openjdk.org/jdk/pull/20486#issuecomment-2292974424
