This reverts commit c45f9ed446.
The kwin rules setting causes all desktop windows to have window decorations. Revert this for now until we figure out a solution.
Replace the convergentwindows KWin script SSD toggling with KWin rules to ensure
windows are maximized and have no window border (and toggle off for
docked mode). KWin rules work immediately at window creation, which is
more efficient than listening to window creation events and manually
changing properties on them.
Currently, window rules setting maximization don't seem to address all cases where a window gets unmaximized, so for the time being we will still need the logic in convergentwindows to handle any sidecases.
This fix maximizes the current window if it ever leaves a fullscreen or maximized state. This is to fix a bug where if a window exits fullscreen mode, it will not return back to a maximized state.
See https://invent.kde.org/teams/plasma-mobile/issues/-/issues/256
We have a race condition between maximizing and disabling window decorations on a window (the calls aren't blocking).
Workaround this by having the window already be in maximized size before we disable window decorations.
