1308540 - ctx.fillText stopped working with FF 49.0.1

Status: RESOLVED DUPLICATE of bug 1304353

(Firefox :: Untriaged, defect)

Description

[Nawshad Jamil]

User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:49.0) Gecko/20100101 Firefox/49.0
Build ID: 20160922113459

Steps to reproduce:

An example will clarify the issue. The following example code used to work in FF until latest version. It still works fine in chrome.
https://jsfiddle.net/DirkWeber/nnqc8/1/

Note that this is not our code - someone else did this example a long time ago. But our code on a web application we developed follows the same principle and uses the same function - ctx.fillText to generate text shadow and manipulate it. After the latest version of FF was released ctx.fillText stopped working. If we replace fillText with strokeText the shadow effect starts working.


Actual results:

We developed a web application long time ago that used to work great until latest version of FF. The application uses ctx.fillText to generate text shadow and manipulate it and it is used by thousands of paying customers everyday. After the latest release ctx.fillText stopped working in combination with ctx.shadowColor.


Expected results:

ctx.fillText should work in combination with ctx.shadowColor to generate a shadow effect like in this jsfiddle example which now only works in Chrome and older version of FF: https://jsfiddle.net/nnqc8/568/
