This is caused by the droid fallback fonts. It seems that the chars covered by droid fallback fonts are not complete, so libreoffice is busy substituting thus caused the delay.
See my comments in https://bugs.freedesktop.org/show_bug.cgi?id=70857. Callgrind debug info in the bug report. ** Bug watch added: freedesktop.org Bugzilla #70857 https://bugs.freedesktop.org/show_bug.cgi?id=70857 ** Changed in: libreoffice (Ubuntu) Status: Invalid => New -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to libreoffice in Ubuntu. https://bugs.launchpad.net/bugs/1258368 Title: libreoffice: long time delay for properties window when set UI language to zh_CN Status in “libreoffice” package in Ubuntu: New Bug description: When zh_CN (Simplified Chinese) language is enabled for LibreOffice UI, the property windows will freeze and take much long time (more than 10 seconds) to show up. This happens in my two home laptops and one office computer, all of which have Ubuntu 13.10 installed. It was the same when I was using Ubuntu 13.04. This issue has been tested by someone else in an official LibreOffice QQ Qun in many other linux distributions and found no problems, so this is a Ubuntu specific bug, not a libreoffice bug. Steps to reproduce: 1. Install LibreOffice with zh_CN lang pack ( no matter whether you install the LibreOffice offical builds, or by apt-get from ubuntu repo); 2. Start LibreOffice Calc to create a new spreadsheet. Make sure the UI language is Simplified Chinese. (If not, change the UI language in LibreOffice options menu); 3. In any cell, right click -> "单元格属性" (Format Cells). Current behaviour: The "format cells" window takes more than 10 seconds to show up. (Actually, it's the same for other formatting properties window, i.e. chars, page, paragraphs, etc.) Set LibreOffice UI language to English will solve the problem. Expect behaviour: The "format cells" window should show up instantly within 2 senconds, as it is for English UI. System Info: Ubuntu 13.10 x86. (Same for 13.04, as well as x86-64). Maybe OK before ubuntu 12.04. Same issue no matter the system locale is zh_ch or en_US. See Also: I filed a bug in LibreOffice bug tracker earlier, but then found this is not their bug.
