description |
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.
---
$ lsb_release -rd
Description: Ubuntu 22.04 LTS
Release: 22.04
---
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).
Source code for a minimal Java application, for which the problem can be reproduced, is attached. Download the provided JTextFieldTest.java file, then from terminal prompt execute 'java JTextFieldTest.java' (Java 11 or later is required, command should be executed from the location of the downloaded file). App's window with a text field will be opened. Click with mouse on the terminal window, then press Alt+Tab and enter some text.
Expected result: focus is switched to Java app's window, and text appears in its text field.
Actual result: Java app's window is raised, but focus stays in terminal window, and typed text appears there. |

------
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.

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.
