First of all thank you all for continuously providing fresh KDE compilations for openSUSE. In my case for openSUSE 12.2.
Problem: KDE 4.10.x: Whenever I switch from an active window to another (inactive) one the title bar and the corner frame are _animatedly_ getting colored, what takes _too much_ time before the window gets active/usable. This applies to all open windows (e.g. Firefox, konsole, smplayer, Thunderbird, dolphin, ...) and to starting ones. No way to turn this off?!
Workaround: Downdgrade to KDE 4.9.5. The problem described above doesn't occur with 4.9.x.
As Luca said there are basically two suspects.
Either some desktop in 4.10 effect does not work very well with your particular gfxcard/gfx driver. So try turning off all effects and see if it changes anything. Later you can turn them back on one by one until you find which one messes things up.
Or assuming you're using the default Oxygen window decoration, try running 'oxygen-settings' and turn off the animations, which might also be slow and annoying depending on your gfxcard/gfx driver
Sorry for answering so late. I'd like to answer to all your posts in one mail, as some posters didn't CC me. I needed some time to figure out what all your hints were for and to test them. Maybe I've never had gotten the clue to what "Compositing" in KDE meant before reading all your answers. @ Martin Schlander: * Using the Oxygen-deco (and disabling all eye-candy with 'oxygen-settings') extremely improves performance over _Plastik_<-- what I used before * And... I'd need more time to 'like' the Oxygen Theme, as it's not pretty! * When having these settings, overall "snappyness" or "interactivity" is great now within KDE desktop, but it uses a higher CPU base usage compared with KDE 4.9.5. @ šumski: http://download.opensuse.org/repositories/X11:/XOrg/ is the source of my actual X (regularily updated!). regarding QT: Raster is only useful if using Composite = ON (xorg.conf) AND ENABLING OpenGL compositing in KDE @startup regarding QT: without any compositing, use "native", as "raster" takes too many resources then.
