1026708 - Problem in rendering of border corners since version 29

Status: RESOLVED WORKSFORME

(Core :: Graphics, defect)

Description

[javier]

Attachment: Example code

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:29.0) Gecko/20100101 Firefox/29.0 Iceweasel/29.0.1 (Beta/Release)
Build ID: 20140524000300

Steps to reproduce:

I wrote a DIV with thick borders, each side with different color.


Actual results:

Firefox shows a weird effect in the diagonal line where 2 borders with different colors intersect, like little "steps". The number of these steps varies with zoom.

You can try the example I attached, but I see it in other sites like https://css-tricks.com/examples/ShapesOfCSS/ (Triangle Top Right for example).


Expected results:

The diagonal line should like the same all the way.

I asked a question about this in the support site and one person confirmed it. He says he can see it since version 27.
