&gt; Hate to break it to you, but running a GTK2 app under KDE&#x2F;KWin will still look inconsistent.<p>Certainly, but at least I can be sure that the inter-application[1] inconsistency in terms of overall window behavior&#x2F;L&amp;F is <i>minimized</i> (as far as practical) if the decorations are server-side.<p>... and <i>that&#x27;s</i> a real win, at least from my perspective.<p>Others may place a higher value on the intra-application consistency of client-side decorations. Obviously, if, say, you&#x27;re using KWin, but only GTK&#x2F;Gnome apps you&#x27;re probably going to prefer this option.<p>Thankfully, it seems that KWin[2] is going to allow both and is going to try to standardize a wayland protocol, so that users can choose what they want. Hopefully most Wayland clients will eventually respect this protocol -- we&#x27;ll see.<p>EDIT: I should also just give a shout out to Mr. Gräßlin. He&#x27;s been an incredible boon to KDE. (No affiliation, don&#x27;t know him personally -- just a fan. Hopefully he&#x27;ll read this!)<p>[1] For applications using different toolkits, obviously. Otherwise it doesn&#x27;t really matter much except for misbehaving-application cases.<p>[2] <a href="http:&#x2F;&#x2F;blog.martin-graesslin.com&#x2F;blog&#x2F;2015&#x2F;12&#x2F;server-side-decorations-coming-to-kwinwayland&#x2F;" rel="nofollow">http:&#x2F;&#x2F;blog.martin-graesslin.com&#x2F;blog&#x2F;2015&#x2F;12&#x2F;server-side-de...</a>
