Description: Problem mewnala crashes on X11 systems with GLFW Error: Wayland: Platform not initialized even when building from source with --features x11. Root cause The x11 feature in processing_pyo3/Cargo.toml was only passing it to processing but not to processing_glfw, so GLFW never actually got built with X11 support. What I changed processing_pyo3/Cargo.toml : added processing_glfw/x11 to the x11 feature processing_glfw/Cargo.toml : added the x11 crate as an optional dependency processing_glfw/src/lib.rs : set _NET_WM_WINDOW_TYPE_DIALOG on X11 so tiling WMs like i3 and sway automatically float the window instead of tiling it Note X11 users still need to build with --no-default-features --features x11,static-link for now. Wayland is still the default. Tested on Arch Linux, i3/X11, AMD Radeon RX 6600 XT
