Thanks, upgrading `libmutter-10-0` along with a couple of dependencies did help.
There is weird caret blinking on switching from Terminal to IDEA (as if the former briefly regains the focus between ultimately relinquish it), but I can live with it. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1971693 Title: Alt+Tab is broken for Java (AWT/Swing) apps in Wayland session Status in mutter package in Ubuntu: Fix Released Status in mutter source package in Jammy: Fix Committed Bug description: Impact ------ When switching to a Java UI application using Alt+Tab, very often application's window is raised, but it doesn't get keyboard focus - it stays in the previous application, and that application continues to process keyboard events. When the problem occurs, hovering mouse over Java app's window gets the focus transferred to it. This problem only happens in Wayland session, not in X.Org session. It can be reproduced in Ubuntu 22.04, but not in 20.04.4 version. The problem seems to affect all Java versions - reproduced for different OpenJDK builds (8, 11, 17, 18). It can also be observed for Java version provided by Ubuntu's 'default-jre' package (11.0.15+10-Ubuntu-0ubuntu0.22.04.1). Test Case --------- 1. sudo apt install default-jre 2. Download the minimal test case app from comment #1 3. From a terminal run the app java Downloads/JTextFieldTest.java 4. Click on the terminal window (instead of the Java app) 5. Press Alt-Tab to switch focus back to the Java app 6. Type a few characters. The characters should show in the Java app's text field instead of in the terminal window.
