I think it might be rather related to Ubuntu's patches (not necessarily to jEdit but to the window management).
I've stopped using Ubuntu a while ago (using Arch Linux now), and jEdit for even longer (using Vim now). I've just seen this bug report, because I was subscribed to the package as a previous uploader, but won't look into this issue. You could try installing the upstream jEdit package - maybe it has been fixed by now and/or it works around some Ubuntu patches (sorry, I have not checked if there are any). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1626068 Title: JEDIT causes an extra icon to be display in the left upper corner (line 2) which covers up "close" icon To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/jedit/+bug/1626068/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
