#1151: Preferences › Performance › Linux display server opens the window through Xwayland, where file drops work

winit 0.30 delivers no file drops on native Wayland. The new Linux Display
Server preference (Automatic / X11 (XWayland), shown on Linux only, read at
startup) has winit open the window on X11 when the session is Wayland,
DISPLAY is set and the X11 libraries winit loads are installed (ldconfig
check ported from PhotoCraft); otherwise the window opens on Wayland and
the log says why. README, development notes, parity docs, ROADMAP and the
complete catalogs updated.
