3 weeks ago Thanks for the report! Unfortunately, this is something I'm aware of and, confusingly, this is a bug in the client-side decoration library we use, libdecor: https://gitlab.freedesktop.org/libdecor/libdecor/-/issues/63
To put it simply, this library handles the drawing for us by wrapping the window object inside its own thing, so that it can handle resizes and whatnot. When SSDs are available, it "soft-disables", making the wrapper "transparent".
It unfortunately looks like the fallback code doesn't handle borderless windows very well.
I'm not sure that much can't be done outside of fixing the code upstream or making our own CSDs, which isn't trivial yet.
Tested versions
System information
Godot v4.3.beta2.mono - Fedora Linux 40 (KDE Plasma) - Wayland - Vulkan (Forward+) - dedicated NVIDIA GeForce RTX 3070 (nvidia; 555.52.04) - AMD Ryzen 5 5600X 6-Core Processor (12 Threads)
Issue description
Probably really niche, but found this problem On KDE Plasma 6, if I specify to use the Wayland display server, (non fullscreen) borderless windows are not borderless I'm neither expert on Wayland nor know how is it being implemented in the engine, but maybe is it because on Wayland Display server it uses Server Side Decorations? I saw issues for Gnome users that had the opposite problem ( #89793 ) (probably because Gnome doesn't do SSD) so I thought it's that ?
