VS Code is like the absolute greatest Electron app that has ever, or will ever be written.

And yet it had an issue for quite some time where animating the cursor flashing was taking an enormous percentage of CPU.

It is also one that has big chunks of C++ and Rust code, and WebGL based rendering to make it actually usable.

Oh you can do that with Electron? This is not my area of expertise... Are there any other ways to have GPU acceleration?

Here how WebGL is used for the terminal in VSCode,

Or how Rust is used for search via ripgrep.

Rendering webpages is already GPU-accelerated by default in most browsers and platforms.

To be fair it was partially related to a bug in Chromium, and was fixed in 2017
