Thank you for taking the time to report this bug and helping to make Ubuntu better.
I have been trying to track down which component/application is actually responsible for creating and maintaining /com/ubuntu/user-interface /scale-factor, but so far no luck. It seems to be related to Unity according to the few Google results I can see, so the question is whether a package failed to remove/move that setting or if OpenJDK should change what it looks at and/or in which order. OpenJDK currently looks for: - /com/ubuntu/user-interface/scale-factor - com/canonical/Unity/Interface/text-scaling-factor - org/gnome/desktop/interface/text-scaling-factor in that order, using the first one it finds. Weirdly enough it does not look for org/gnome/desktop/interface/scaling- factor. These changes were introduced by JDK-8149115 in commit http://hg.openjdk.java.net/jdk/jdk/rev/a3cc7e551a48 but neither the bug nor the Mailing list discussion state why they picked those items and in this particular order. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to unity-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/1765914 Title: Java windows and fonts are huge running in openjdk-11-jre Status in openjdk-lts package in Ubuntu: New Status in unity-settings-daemon package in Ubuntu: New Bug description: If I run a Java application with oracle-java-8 in an X session, the windows and fonts are all normal size. When I run the same application with openjdk-11-jre, everything is scaled up to double size (see attached image, which shows an application on the left running in Java 8 and the same application on the right running in Java 10 (from the package openjdk-11, not openjdk-10 for some reason). My normal screen layout is 1920x1080 with two screens, so the command "xrandr -q | awk -F'current' -F',' 'NR==1 {gsub("( |current)","");print $2}'" shows 1920x2160. One of the screens is 4K, so presumably Java *might* be detecting this and deciding it needs to double everything in size, but this is clearly an error since I'm not even using this mode. If I set the laptop to use a single external 1920x1080 monitor, it makes no difference - the Java applications are still double the size that they should be. There's no problem if I run in a Wayland session - the app windows run at a normal size whether in java 10 or 8.
