Description syuki 2010-02-20 01:13:06 UTC
There seems to be a problem with line height calculation for Japnese fonts in
Open Office 3.2.0.

I noticed it because it uses my system font for the UI. The menus and item lists
have an unusual line height. I am sending a snapshot with my system menus and
Open Office menus. I have noticed that all Japanese fonts have that problem, in
the menus and in the editing window - some less than others, but they all
display differently in OpenOffice.

Firefox had the same problem until I opened the advanced settings and turned
browser.display.normal_lineheight_calc_control to "0" (disabling it).
What about implementing such an option in Open Office until you are 100% sure
the line height calculation works right?

I have also noticed that MS Gothic (Microsoft's) is the only font that displays
correctly... But measuring the success of the line height calculation on that
font only is not really a good idea...

@ sba: Please have a look.
