It's Linux, Ubuntu 20.10. Neither can I. I checked the history and the test failed on different hosts, so it could be an intermittent bug in JDK itself. ~~Shouldn't the image be larger than 400×300? The size of the frame is 400×300 in user's space, the test is running with uiScaleX=3 and uiScaleY=2, therefore the size of the frame should be 1200×600. In some cases, such a size may not fit on the screen.~~ I see these `sun.java2d.win.uiScale{X,Y}` affect Windows only. On Ubuntu, the test runs according to the system settings. ------------- PR: https://git.openjdk.java.net/jdk/pull/7613
