Hi everyone, I observe a somewhat strange behaviour of my plasma desktop: When I try to switch between applications (say Dolphin and Firefox) I have to sustain a delay of several seconds on my desktop pc. It is definitely not a hardware issue, because my machine is about six months old (Six-Core AMD FX-6200 with 3800MHz, 8GiB Memory, 12 GiB swap space on a 1.5TB SATA-disk), further the behaviour does not occur on my notebook, which has much less perfoming hardware. The behaviour does not occur from the beginning, but later on, I suspect after the screen-saver has been called for the first time. However the effect is reproducible. I used the KDE system monitor for diagnosis. I found out that when this occurs, one of the six CPUs is always at 100%. The responsible process is obviously plasma-desktop, which is always at 17% CPU. The effect occurs only when trying to switch applications using the mouse on the "Startleiste", ALT+TAB works like it should. I am willing to provide more detailed information, but I need some help from developers, how to do that. Finally some informations on my system: OpenSuSE 12.3, x86_64, fully updated from the communitiy repos. KDE 4.10 kdebase4-workspace-4.10.0-1.8.1.x86_64 (where plasma-desktop belongs to) Kernel: 3.7.10-1.1-desktop #1 SMP PREEMPT Thu Feb 28 15:06:29 UTC 2013 (82d3f21) x86_64. Any help is appreciated.
