707508 - Firefox often render line height with a 1px inaccuracy

Status: RESOLVED DUPLICATE of bug 442139

(Firefox :: General, defect)

Description

[Ian Yang]

User Agent: Mozilla/5.0 (Windows NT 6.1; rv:8.0) Gecko/20100101 Firefox/8.0
Build ID: 20111104165243

Steps to reproduce:

Apply css declaration "line-height" to text.


Actual results:

Firefox often render line height with a 1px inaccuracy in random line gaps than other browser. The result is correct in Chrome, Safari, Opera, and even in all IE.

In fact, this issue has existed for a very long time. From I can remember, since Firefox 2.


Expected results:

Firefox should render line height like other browsers do.

Duping, please correct the resolution if you think it's wrong. Thanks!

Thank you. However, I don't have to "correct" resolution to get correct results on other browser. How come it is required to do so to get Firefox behave correctly?

I meant the "Duplicate" resolution of this bug, not your screen resolution. 
There is no way to work around bug 442139 other than specifying line-height in pixels (and avoiding zoom).

Thank you. I see. Is this a problem of mozilla engine (or whatever)? And when will this be fixed?

Nobody knows. Watch bug 442139, especially the "Target Milestone" field.
