Can you check if the problem still appears with unclutter 8-19? It's available from Saucy onwards.
See http://packages.qa.debian.org/u/unclutter/news/20130502T003252Z.html (or https://bugs.launchpad.net/ubuntu/+source/unclutter/+bug/385034) for the changelog entry. According to http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=266118#17 the patch applied in 8-19 has a similar effect as -noevents except that it still works with some more window managers. With regards to -grab: That can causes similar problems, so I'm reluctant putting this in by default. BTW, the issues fixed in 8-19 don't affect all XULRunner applications as it e.g. doesn't affect conkeror (only available in Debian) while Firefox/Iceweasel does have known issues in combination with unclutter 8-18. But these issues are flickering as reported in https://bugs.launchpad.net/ubuntu/+source/unclutter/+bug/385034 ** Bug watch added: Debian Bug tracker #266118 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=266118 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1255507 Title: Running unclutter without "-noevent" causes focus problems for Firefox and Thunderbird To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unclutter/+bug/1255507/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
