kwin-wayland binary package in openKylin Nile.bedrock amd64

 KWin (pronounced as one syllable "kwin") is the window
 manager for the KDE Plasma Desktop. It gives you complete
 control over your windows, making sure they're not in the way
 but aid you in your task. It paints the window decoration,
 the bar on top of every window with (configurable) buttons
 like close, maximize and minimize. It also handles placing
 of windows and switching between them.
 .
 This package provides the wayland version, which is still a work in progress
 project, and is available as a PREVIEW release. Don't expect the same
 stability as with the x11 version.
