"This is an introductory overview post for the Linux Graphics Stack, and how it currently all fits together. I initially wrote it for myself after having conversations with people like Owen Taylor, Ray Strode and Adam Jackson about this stack. I had to go back to them every month or so and learn the stuff from the ground up all over again, as I had forgotten every single piece. I asked them for a good high-level overview document so I could stop bothering them. They didn't know of any. I started this one. It has been reviewed by Adam Jackson and David Airlie, both of whom work on this exact stack." Introductory or no, still pretty detailed.

Just like in any version of Windows you mean? 
I think we can live with applications lagging when they hang. It's applications lagging when they're behaving normally that is of concern IMO.
As for Wayland, I still find the idea of mainstreaming a display system that only works on Linux... irksome. There are other UNIXes out there, some with advanced features that Linux doesn't have, and a much better record in terms of security and stability. Dropping support for them entirely is not what I consider a wise move.

I think you mean that XP & earlier use a stacking window manager so not redrawing when the application hangs. Wayland of course is for compositing WMs. But anyway, like you say, who cares if a window is a bit jittery while you drag it around the screen. If it's the kind of thing you do a lot (like me) then you probably have other problems...
I totally agree about the Wayland framework leaving the BSDs out in the cold being a bug, not a feature.
However, I don't really understand why all the Wayland comment threads here because the original article is not wayland advocacy, it's just one of the relevant things covered within an overview of the graphics stack.

At an event earlier today, Microsoft unveiled the next Xbox - the third model, but confusingly named Xbox One. The big focus was TV, integrated Kinect, and all the other stuff we all expected to be forced down our throats. I think it took them 25 minutes to actually come to what should be the core of the story: gaming. Nothing groundbreaking in the gaming department, except for how Microsoft intends to handle the used games market and borrowing games from friends: pay up, buddy!

The day has finally come! Jolla has finally announced the launch device for its Sailfish operating system - and by god this is a looker. It's decidedly different from other phones out there, but it has good specifications and carries a relatively reasonably price tag - EUR 399, and it's up for pre-order today, shipping in the fourth quarter of this year.

Why does Google get so much credit in the technology industry? Why, despite the company's many obvious failings, do many geeks and enthusiasts still hold a somewhat positive view on the all-knowing technology giant? A specific talk at Google I/O this week provides the answer.

"Windows is indeed slower than other operating systems in many scenarios, and the gap is worsening." That's one way to start an insider explanation of why Windows' performance isn't up to snuff. Written by someone who actually contributes code to the Windows NT kernel, the comment on Hacker News, later deleted but reposted with permission on Marc Bevand's blog, paints a very dreary picture of the state of Windows development. The root issue? Think of how Linux is developed, and you'll know the answer.

This is one of those news items that's fun to write, fun to read, fun to comment on, and where no one will be able to say anything unkind. It's all just one big ball of awesome fluffiness. TuneTracker, the BeOS radio automation software, has just released something very special: TuneTracker System 5, the first version designed entirely and specifically for Haiku. In fact, it actually includes Haiku in the software package. Better yet, TuneTracker also unveiled several system-in-a-box products - which have Haiku and TuneTracker pre-installed.

Exactly twenty years ago, a document was published that played a huge role in establishing the web as we know it today. Twenty years later, and this simple and straightforward document is proof of an irrefutable fact: while closed technologies can change markets, open technologies can change the world.

Oh multitasking. That staple of computing that got thrown out the window with many modern smartphones. We got some rudimentary thing in its place - but even as multitasking on phone and tablets improves, its user-visible side remains cumbersome. Windows 8 has a neat implementation, and now it's time Android follows in it footsteps.

They're here! Whether that excites you or not remains to be seen, but the Galaxy S4, which will most likely become the best selling Android smartphone of the year by a huge margin, has been reviewed by all the major sites, and there's lots of interesting conclusions in there - although I think most of you will get the gist.

Nokia has posted its quarterly results for the first quarter of 2013, and just like the quarters that came before, there's not a whole lot of good news in there. The rise in Lumia sales still can't even dream of making up for the sales drop in Symbian phones, and when broken down in versions, the sales figures for Windows Phone 8 Lumias in particular are very disappointing. In North America, Nokia is getting slaughtered.More Features »

Wayland has some downsides too:
do you know what happens when you try to move a Window of a busy application in Wayland?
Since Wayland is designed with compositing window managers in mind, I would hazard a guess that a static, screenshot-like bitmap of the busy window is moved around, without needing to constantly refresh that bitmap as with older WM technology. "
Wrong, remember that the decoration is handled by the application in the "normal" Wayland configuration.
So the application is handling the mouse events (then tell to Weston move my Window), so if the application is busy, moving a window may be laggy/"not smooth".
