What is the GUI update interval set to in the advanced settings ? Default 1000ms. Increasing it to 5000ms to make it behave. But then the GUI isnt exactly responsive. I can't reproduce this problem, Xorg hardly uses any CPU with the peers tab shown. How many peers are being shown when this happens ? Its mostly independent of number of peers shown. One or two peers in the peers tab and Xorg goes to 100%. Switch to another empty tab like webseeds and Xorg uses 20-30% according to top. Minimize ktorrent to the system tray (not only minimize window) and Xorg pretty much disappears from top listing FYI : [ 15.107292] fglrx: module license 'Proprietary.

Maybe the kwin people have some idea what is going on, so reassigning to them. sth. will likely repaint in a loop - what is an expensive operation on a composited desktop (requires damage event handling and pixmap -> texture conversion) but is neither "cheap" on an uncomposited desktop either. a) press "shift+alt+f12" the compositor will suspend and the Xorg cou load should drop. b) run "kcmshell4 kwincompositing" and in "all effects" activate "show paint" (WARNING: this will cause colorful flicker on your screen, so do not do this if you suffer from epilepsy) As result some region on the screen (inside the ktorrent window) will likely flicker a lot - that's the item with the high repaint frequency (probably some animated progressbars or so) what did the show paint effect indicate?

Xorg puts an unusual load on CPU whenever KTorrent's main window is displayed, something in the 50-100% range. Unloading all the plugins won't fix anything, but as soon as I minimize KT, Xorg soars down to 1% or less. Same problem with both Nvidia binary drivers, nv driver and AMD fglrx. Problem specially noticeable when the Peers tab is populated and selected Reproducible: Always Steps to Reproduce: 1.Start KTorrent and download a popular torrent.
