There's a major slowdown for the 3.1.1 version when AA is active and it needs to rerender images: https://bugs.launchpad.net/ubuntu/+source/openoffice.org/+bug/411542
Try disabling AA as described in that bug and see if it helps. For what it's worth I can use Japanese glyphs with AA disabled without any slowdown problems. -- Impress unusably slow with Japanese fonts https://bugs.launchpad.net/bugs/468212 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
