With Alt+tab the gain focus of the title is slow. I first noticed this after upgrading to kde 4.10 The title rendering seems to work in two steps: - render shadow - render active state This process takes a full second. This really bugs my alt+tabing, I can't directly recognise where and which window has gained focus. I have disabled all animations, but this doesn't change the non-instant rendering of the gain focus. Switching between xrender and opengl seems to only make smoother. I have this both on my intel card and the nvidia one. The same seems to be true for the window losing focus but in reverse Reproducible: Always Steps to Reproduce: 1. Have two windows side by side 2. Have focus on one window 3. Press alt+tab 4. Watch rendering of the other window title (and the first) Actual Results: slow two step rendering of the title gaining focus Expected Results: instant active state of title bar of window that gained focus
You missed to tell about your custom settings. Which window switcher do you use? Which deco? Which animations did you disable? KWin animations? Style animations? Deco animations? (the last one might be the one you missed...) Having said that I can't see anything slow here. I have enabled the animations of oxygen-kwin-deco (with the default of 150ms for the transition) and everything is smooth and easy to recognize.
Thnx for your reply! (In reply to comment #1) > You missed to tell about your custom settings. > Which window switcher do you use? Which deco? custom settings? Window switcher visualisation is informative I use the Oxygen theme + plastik decorations > Which animations did you disable? KWin animations? Style animations? Deco > animations? (the last one might be the one you missed...) Desktop effects: -> General -> enable desktop effects at startup (disabled) -> improved window managenemnt (disabled) -> various animations (disabled) -> effect for desktop switching: no efftect -> animation speed: instand -> All effects, all are disabled -> Advanced -> compositing: Opengl -> qt graphic system native -> opengl options: use shaders / use vsync Where would I find any other settings for animations? > Having said that I can't see anything slow here.

What I am experiencing may be less then a full second (at least half), but is still clearly visible. I hope this helps
kcmshell4 kwindecoration That's where you can configure your deco. BUT: Plastique does not offer setting animation duration. If it is not smooth you might want to report it to bugs.kde.org (AFAIK plastique is a QML decoration, so it should be smooth if your graphics driver is OK - how are desktop effects running for you?). One (IMHO good) option would be to adapt QML animation speed to the generic effect speed. If you select oxygen deco you can disable animations in the deco completely.

If I change the decorations to oxygen the problem seems to completely disappear! Though the color of the titlebar doesn't switch between active and non-active at the moment. I'm going to play with the settings later. The desktop animation performance was bad with both on x11-drivers/xf86-video-intel-2.20.13 and x11-drivers/nvidia-drivers-313.30. All animations (start/are) very slow/jittery. I will check when I restart X if this changes with other decorations.

I tried several and they all work fine except for the Plastik one. Thnx!
Well... I knew I read something about plastik deco... Here you are: https://bugs.kde.org/show_bug.cgi?id=314532 Fixed in 4.10.2 I would suggest to reopen this bug report as it is a clear regression.

I'm using KDE 4.10.1, that is the current stable in default/linux/amd64/13.0/desktop/kde So I couldn't say anything about a regression yet ;)
