I can run any app with WAYLAND_DEBUG=1 and understand every message easily. > because of the strange priorities it has worse performance than X11 If the performance that matters to you is the tiny bit of latency caused by vsync, keep using Xorg, or Windows 95, or whatever. Wayland is inherently much faster because it's asynchronous and doesn't have anything in between the compositor and the clients (e.g.: app <-> Xorg <-> Compiz — xorg is just a glorified message broker!). > wlroots library has more than 50000 LOC, all for moving around a bunch of overlapping windows? A bit much Minus 8.5k for examples, minus 7k for the big example (rootston). It's not just moving windows around. Input is inherently complex, and it supports touchscreens, touchpad gestures, drawing tablets, virtual keyboards, pointer locking (moving the camera with the mouse in first person videogames).. Also, it implements multiple backends — running on KMS/DRM, nested on Wayland and X11, and as an RDP server. Considering that it's all in C, that's a tiny number of lines. More importantly than silly metrics, it's a modern, easy to get into codebase. How much does Xorg have, with its five or however many input systems, multiple legacy ways of direct rendering, and whatever other crap it's accumulated? |
