#3714 Keyboard not working after refocus, Linux+Compiz

Przemek Wesolek

After I upgraded to Java 7, jEdit stopped to respond to key events after re-gaining window focus.

After selecting View-New view, in the opened view everything works fine (until refocusing again, of course), in the old view the problems persist.

What doesn't work:
- entering text in text area
- shortcuts
- navigating menus after mouse-clicking on menubar

What works:
- text entering and keyboard navigation in dialogs

Steps to reproduce
1. Start jEdit cleanly
$ rm new.settings
$ mkdir new.settings
$ jedit -settings=new.settings
2. Focus on text area by clicking inside (don't close "jEdit Help" window!)
3. Try typing (new characters appear in text area) or hit any shortcut (works)
4. Lose focus (either Alt-TAB to other window, or click with a mouse on other window or desktop)
5. Gain focus (either Alt-TAB to jEdit window, or click with a mouse on jEdit's text area)

  • Also confirmed on SVN trunk as of today.

  • I think this has something in common with Compiz running.

    There are numerous bugs filled for JRE, Netbeans or Compiz considering cooperation between Java and Compiz. What makes me think that this bug is belonging to the same family of problems is that I can workaround the problem by restarting Compiz *after* jEdit is running:

    $ jedit
    $ compiz --replace

  • Maybe related to #2676950?

    Can not reproduce in current Debian Testing with KDE 4.8.3, java version "1.7.0_03"
    OpenJDK Runtime Environment (IcedTea7 2.1.1) (7~u3-2.1.1-1)
    OpenJDK 64-Bit Server VM (build 22.0-b10, mixed mode)

  • Alan, do you use Compiz? My investigations show it's probably a Java-Compiz issue.

    Moreover, I noticed the same problems yesterday with JabRef (also a Java app).

    I propose to mark as invalid.

    KDE 4.2 does not use compiz. It has its own compositing system.

    closing as invalid. Resolution: don't use compiz.

  • Oh, please...

    The same problem with Ubuntu 12.04 LTS + GNOME2 + icewm: the keyboard works only in Dialogboxes. Tried with openjdk 7u9-2.3.3 and Oracle JRE 1.7.0_10.

    But Java 6 works (Oracle JRE 1.6.0_38)!
