CirnoT reported how they felt that GTK3 is not reliable on Windows.
Seeing some weird issues where clicking Deluge icon on taskbar does
bring window to front but doing so again does not minimize it as one
would expect. By using GTK_CSD=0 this would reduce these problems.
> If changed to 0, this disables the default use of client-side
decorations on GTK windows, thus making the window manager responsible
for drawing the decorations of windows that do not have a custom
titlebar widget.
This can be overridden by a global env var.
