Status: RESOLVED DUPLICATE of bug 895096

(Core :: Layout: Tables, defect)

Description

Attachment: Contains html and css files

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:25.0) Gecko/20100101 Firefox/25.0 (Beta/Release)
Build ID: 20131112160018

Steps to reproduce:

Created a simple 3-column table with borders 1px solid


Actual results:

The bottom border of every 4th cell is thickened to what seems 2 px. Except that this first occurs at the bottom of the 3rd cell (see included HTML table). This does not occur when I open the same HTML table file in Opera or IE 11.


Expected results:

All cells should have same thickness of 1 px in top and bottom borders.

PLease use 100% default zoom and report back. The problem only happens with some increased zoom level.

I installed Default FullZoom Level 5.8 add-on in order to know which was the 100% default zoom. (I did not change the default zoom). As you see, at 100% zoom the original problem is duplicated. It goes away at 80% zoom and at 133% zoom, *every* horizontal cell border is thickened.

Can anything be modified so that there is no line thickening at 100% zoom?

"Ctrl+0" shows the default zoom. No add-on required.
