In CJK text, normal line height is too small and does not looks very good. Bug 76097 is filed against windows, and there is long discussion there. This bug is filed against linux. I would suggest to fix this problem after we found satisfied solution for both bug 76097 and bug 156943. Hideo saito has posted some patched in 76097, please refer that bug for detail.

Is this just for line-height? cause there is another bug 110826 for underline problem, but I'm not quite sure the patch over there is for line-height or underline.

This is for lineheight, and that one is for underline position.

Is it necessary to add mExternalLeading and mInternalLeading to nsFontMetricsGTK like nsFontMetricsWin in bug 76097? How about other platforms?

nominate this as nsbeta1.

See bug 137817

Yuying, is it a page view enchancement or the display is wrong?

The display is not wrong but the CJK pages looks ugly without fix. Bug 76097 and bug 15643 have some screen shots to show the problem.

Marking as resolved (dupe of bug 218032) I know this is backward, but I didn't know the existence of this bug before filing bug 218032 and spending a lot of time there. (I didn't read through the end of bug 76097 ;-)) *** This bug has been marked as a duplicate of 218032 ***
