KDE4 slow as user, root is fine

KDE4 runs annoyingly slow when logged in as a normal user. When logged in as root it just flies.
For example resizing a terminal (dragging with mouse) goes instant as root but takes forever as user. It just seems really unresponsive for some reason.

KDE4 is installed from experimental on Debian SID as described on

Any clues on where to look for the solution?

KDE4 is installed from experimental...
Then your answer is in front of you:

If you are going to run "experimental" ( which is not even "maybe just stable enough for a release" ) then you should expect to experience some bizarre behaviour. Please contact the experimental developers (there should be a link from wherever you downloaded the code) and file a bug report there if you wish to be this "cutting-edge".

This is LQ, not "We can fix everyone's bugs".

You don't say much about your installation, such as whether you are running the same things as both users or whether it slowed down as a result of something that you installed or a setting change. The obvious starting point is that root is a user as is your user name. Each would have its own settings stored in the .kde4 folder of each user (/root and /home/username). I would delete the the .kde4 folder from your own home folder while you are logged on as root and then log out and back as yourself. Then set up KDE 4 from scratch. If it starts to slow down again, try to figure out what you did that led to it. It could be something that is loaded as part of your user session or a service that is running in the background. Go to System | Control Panel and click on the Advanced tab to access the Session Manager and Service Manager.

As for the comment that you should not be using experimental, develop a thick skin. Some people crave the ordinary and others like the bleeding edge. Different strokes for different folks. Somebody has to run experimental or we would never move forward. Go ahead as long as you don't mind the associated problems. Getting advice is part of the learning curve and some people don't mind helping.

You might want to consider a dual boot though with a stable release as your main distro, otherwise you will be frustrated if you can't get work done due to bugs, crashes or other things peculiar to experimental releases.
