From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Zed is a modern open-source code editor, built from the ground up in Rust with a GPU-accelerated renderer.

Probably because it's more efficient. GPUs are designed to render things, which editors do. In a text editor, you're effectively rendering fonts over a fixed background, which I assume is pretty efficient using the GPU.

We're not talking about crazy 3D effects here.

Yay to battery savings!

Shouldn't the DE/Window Manager be handling that? Seems like doing it on a window by window basis would be inefficient (and look inconsistent).

That’s a totally unrelated part of the stack. These days you just have a compositor that combines the output of applications.

The model of out of process rendering in Xorg was done pre-2000s but GPUs became the norm and don’t work well this way.

Thats where we get into explicit and implicit sync right?

Also very unrelated, that’s about graphics apis like opengl.

The job of the window manager is to manage windows and very little else. Font rendering is done by the widget toolkit, usually via freetype/harfbuzz.
