    One important thing that was missed... the bug that caused the taskbar to randomly re-arrange and overlap has been officially closed (Whether as FIXED or WONTFIX varies on your perspective lol) no one so far as been able to reproduce the behavior in KDE 4.11-- with the new QML based taskbar. So if you hate that bug you have to upgrade to 4.11 to not be affected by it.

    The biggest thing in this release IMO, is that they have FINALLY fixed tearing on kwin with intel. KDE has been unusable for about a year for me because they've taken forever to get that fix into a release.

    thank god, that bug really annoyed me too. Looks like with this release almost all my issues wth KDE have been sorted out and I can finally consider switching over to it. The only big remaining issue is that dolphin does not mount network shares and no video players properly support kioslaves so streaming videos from a smb share is a PIA compared to with gnome, but that can be worked around at least.

    Bwat, what tearing are you talking about?? I'm running Kwin on Sandy Bridge and haven't seen any tearing. Is it only visible without a compositor? (aka desktop effects disabled)

    Also, are you sure that its not the tearing that Keith was talking about at linux.conf.au? I forget what the exact reason for it was he said THAT tearing wouldn't be fixed until DRI3(000) shipped because it would take "That kind of software" to fix it, which wouldn't be a kwin fix unless they found a work-around.

    Is that why Kwin first has to download the full video THEN play it? Always wondered why that happened... Surprised that DragonPlayer doesn't support kioslaves, hmmm..

    Awesome! That was always a nag I had...though I also use cairo-dock so I had an effective way to work around it. Great news.

    I'm curious as to what you mean by this? I personally prefer to do my network mounts via CLI in any case, however I've helped other people who were new to KDE to mount samba shares through Dolphin and it's actually rather trivial, from what I recall.

    I can't even get it to do this anymore. with the default dragon player (also tried smplayer) opening a video from a smb share in dolphin refuses to play at all. only way to get it to work is with vlc because vlc has its own smb module, but I have other issues with VLC that make vlc unusable for me unfortunately (severe audio/video sync issues when I increase the network cache setting)

    With most other file managers, such as nautilus, thunar, or pcmanfm when you access a network share it mounts it on the fly using GVFS. This makes it so any application can access/play these files because they are treated like local files.

    KDE does not mount the share, instead it browses the shares with its own KIO/Kioslaves system, the problem with this is typically only KDE software supports kioslaves, and in some cases even KDE software doesn't support them well enough (for example dragonplayer doesn't seem to support a smb kioslave and simply fails to play videos from a smb share in dolphin). Gnome's GVFS solution works with ALL software, its far superior.

    I don't find mounting the share in fstab to be an acceptable solution. This is a laptop and the share is not always available, and with a CIFS mount you can get locking up issues in KDE when the share is not available. To me the only acceptably solution is something where I can easily mount and unmount the shares on the fly, as a user. SMB4k is the best I've found so far for kde but its kind of buggy unfortunately.

    I'm talking about this kwin bug: https://bugs.kde.org/show_bug.cgi?id=307965

    If you are using sandybridge with kde you *will* get tearing. Perhaps you haven't noticed it because its restricted to the top part of the screen (and on some screens it might be more noticeable than others). I found it quite noticeable when watching fullscreen videos on either of my intel laptops (one ironlake, one ivybridge), but when using the desktop its not really noticeable.

    It is because of kwin using copysubbuffermesa you get tearing in kwin even with vsync on with intel hardware (because intel has not supported tear-free rendering with subbuffermesa for quite some time now, I believe its been since sandybridge). In KDE 4.11 they've added finally a new rendering path for intel that does not use this, and fixes the tearing. Ubuntu's compiz has had this bug fixed for ages, since the release of ubuntu 12.10. Its still not fixed in gnome-shell/mutter but there is a very easy workaround to fix it there (adding a single line to /etc/environment).

    Good to know, I hadn't tried it in a while I just knew when I HAD tried it I got "Download first then play."

    And for the life of me I can't reproduce this using KDE 4.10.4... But regardless, whether I can reproduce it or not its still apparently a bug to be fixed, and its getting fixed, so thats good.

    (for the record I cant even see it while playing video on a Sandy Bridge 1366x768 12inch laptop screen, so it may be resolution / screen size dependent. With Vsync enabled, btw which is supposed to make the tearing worse...)
