I too had this problem on my Lenovo SL510 with Ubuntu 13.10. However this solved the problem for me:
In Synaptic I found 4 ibus related packages with status 'installed, but upgradable'. I upgraded these, and now the corrupted chars problem seems to be gone. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1227569 Title: individual characters frequently corrupted To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/1227569/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
