The new test added in JDK-8211999 hits a bug on Linux (in mach5 it is passed on ubuntu 18.04 and failed on 20.04). The problem is that the bounds of the fullscreen frame include insets of the frame additionally to the screen size.
The behavior of the decorated full-screen window is not specified: https://docs.oracle.com/en/java/javase/11/docs/api/java.desktop/java/awt/GraphicsDevice.html#setFullScreenWindow(java.awt.Window) But it will be good to have the same cross-platform behavior. So I filed a separate bug to investigate the behavior of decorated frame in the fullscreen mode: https://bugs.openjdk.java.net/browse/JDK-8256257 ------------- Commit messages: - Update FullscreenWindowProps.java Changes: https://git.openjdk.java.net/jdk/pull/1180/files Webrev: https://webrevs.openjdk.java.net/?repo=jdk&pr=1180&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8256201 Stats: 2 lines in 1 file changed: 1 ins; 0 del; 1 mod Patch: https://git.openjdk.java.net/jdk/pull/1180.diff Fetch: git fetch https://git.openjdk.java.net/jdk pull/1180/head:pull/1180 PR: https://git.openjdk.java.net/jdk/pull/1180
