As Robert Collins pointed out, I'm using Ubuntu 10.04 LTS (sorry forget mention that). Evince came with Ubuntu. With these info, one should be easy to reproduce the bug.
Actually, xpdf installed by 'synaptic' or 'apt-get' in Ubuntu also had key-lag problem (pages moving lag much behind key strokes). I downloaded the version from http://www.foolabs.com/xpdf/ and the problem solved. So it seems it's the problem of Ubuntu software repository. -- evince can't show some characters in some (probably old) pdfs https://bugs.launchpad.net/bugs/676798 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
