Not sure how you’re getting no Sway title bar out of it. In fact, when I run `swaymsg border csd` with the tiled gtk4-demo focused, I get “This window doesn't support client side decorations” and I have no idea what’s up with that, especially given that the window definitely gets border csd when floating. ¯\_(ツ)_/¯ It’s possible it’s related to more recent changes in Sway. I haven’t updated Sway since March (since I’ve been using the high-DPI XWayland patches and updating is comparatively bothersome). I dunno. Incidentally, I mostly use tabbed layout, and you’re always going to get server-side decorations out of that, since you’re breaking out of the rectangles mould.
