I think @aivanov-jdk intuition was right. I checked with different uiScales. With this configuration: Left side: Secondary & Right side: Primary screen The test passes on uiScale: 1, 1.25, 1.75, 2 .. and so on... It fails on uiScale: 1.5, 2.5 and every other 0.5 scale increment. Surely looks like a pixel rounding error .. ------------- PR Review Comment: https://git.openjdk.org/jdk/pull/22781#discussion_r1907929765
