WebRender, is a 2D renderer for the web. It started as Servo's graphics engine, and we are in the process of integrating it in Firefox. I have been meaning for a while to write about what WebRender is, how it works and how its architecture is different from what Firefox and other browsers currently do. … Continue reading Introduction to WebRender – Part 1 – Browsers today
We recently enabled off-main-thread compositing on Linux. As I write this post it is enabled on Firefox nightly and Firefox developer edition and if nothing bad comes up it will ride the trains and get enabled in beta and in the stable release of Firefox 40. Web browsers render web content in separate intermediate surfaces … Continue reading Off-main-thread compositing on Linux
As usual, there will be a lot of Mozillians attending FOSDEM this year, including 3 members of the graphics team. Bas Schouten will give a talk about Utilizing GPUs to accelerate 2D content on Saturday (16:30 in the Mozilla devroom). It's going to be a very interesting and also fairly technical talk. If you are … Continue reading FOSDEM 2014

We refer to this as "off-main-thread compositing" … Continue reading Removing old OpenGL layers
I heard we don't have enough mentored bugs filed for the gfx code. If you are interested in contributing to Gecko's graphics code, read on. Contributing to Gecko for the first time can be scary because Gecko is a complex beast and it is very easy to get overwhelmed by the amount of code. Trying … Continue reading Looking for a good first place to contribute to Gecko gfx?
Let's talk about some common misconceptions about hardware acceleration. Hardware acceleration conveys the idea that some parts of the rendering use the GPU in order to speed things up. In a web browser there are two main topics for hardware acceleration: Hardware accelerated content rendering: Drawing content on the GPU, like rendering text, shadows, shapes, … Continue reading Hardware acceleration and compositing
