KDE "Mobile devices that adapt to who you are, reflecting what you are doing when you are doing it. This concept is at the heart of the Plasma Active user experience. Plasma Active One was released in October 2011, providing early adopters the first opportunity to experience Activities on a tablet. Since then, the design and development team behind this open source touch interface has been hard at work on an update. The fruits of their labor were released today, December 14, 2011 as Plasma Active Two."

I have more than one system running, xfce, gnome 3, razor-qt, but preferably KDE since it is the more usefull desktop. All desktops are speedy, except kde. On all desktops but kde elements pop-up without waiting, both on the open source nvidia as well with the closed binary driver. If I recall correctly, I'm not the only one complaining about performance problems with plasma (and kwin). They're working on it, it clearly improves with every version, however they still have a long way to go when it comes to performance.


No, they don't. Your system simply doesn't perform correctly for some particular operation which happens to be used by KDE but not other desktops. This exact same operation is performed correctly on millions of other systems which run KDE just fine.

Thom has had a similar long-term issue on his main system. The author of kwin Martin Gräßlin had a look at this for Thom (presumably using a profiler), and I am told he identified the issue was within the functions called up by the snap functionality (the Windows 7 Aero Snap stuff KDE also implemented). Martin had never seen this problem before. The interim workaround for Thom is to disable the snap functionality.

Please note that this functionality works just fine as it is for millions of KDE users. If Martin can identify a workaround within KDE itself that does not penalise the millions of other users, then perhaps Martin might modify KDE's code with this workaround in order to have it work also on the relatively few systems (including Thom's) that are affected. The ideal solution, however, would be to get this fixed at the point where it is actually broken, wherever that turns out to be, rather than penalise millions of KDE users by disabling the working snap feature for them also.
