It can be found at https://bugs.launchpad.net/bugs/471597 The report is about emacs 23.1 but I still have the same problem with the pretest version 23.1.92. It is weird that this symptom occurs only if I use the particular bitmap font, baekmuk. However, this font causes no trouble when I am using emacs 22. For your convenience let me copy the text below. The attached file is available at the above link. Thank you. Jae-hyeon Park Binary package hint: emacs23 Source package: emacs23 Ubuntu release: 9.10 amd64 Package version: 23.1+1-4ubuntu3 I use the bitmap font xfonts-baekmuk to display Korean characters in emacs. When there are many Korean characters in a buffer, moving the cursor among the Korean characters takes a long time (like a few seconds on my laptop which is a fairly new hardware). How to reproduce: 1) Start emacs with $ emacs23 -Q -xrm 'Emacs.FontBackend: x' & 2) In the scratch buffer, evaluate the following code (create-fontset-from-fontset-spec "-misc-fixed-medium-r-normal--15-140-75-75-c-90-fontset-baekmuk, ascii:-misc-fixed-medium-r-normal--15-140-75-75-c-90-iso8859-1") (set-fontset-font "fontset-baekmuk" 'korean-ksc5601 "-baekmuk-gulim-medium-r-normal--18-180-75-75-m-180-ksc5601.1987-0") (set-frame-font "fontset-baekmuk") 3) Open the attached file in the same frame 4) Try to move the cursor downwards by pressing C-n several times
